## WCM Templates

### Content types

Overview

The templates are applied to a node type or a metadata mixin type. There are two types of templates:

- Dialogs: are in the HTML form that allows creating node instances.

- Views: are in the HTML fragments which are used to display nodes.

From the ECM admin portlet, the Manage Template lists existing node types associated to Dialog and/or View templates. These templates can be attached to permissions (in the usual membership:group form), so that a specific one is displayed according to the rights of the user (very useful in a content validation workflow activity).

Document Type

The checkbox defines if the node type should be considered as the Document type or not. Content Explorer considers such nodes as user content and applies the following behavior:

- View template will be used to display the document type nodes.

- Document types nodes can be created by the 'Add Document' action.

- Non-document types are hidden (unless the 'Show non document types' option is checked).

Templates are written by using Groovy Templates that requires some experiences with JCR API and HTML notions.

#### Dialog

Dialogs are Groovy templates that generate forms by mixing static HTML fragments and Groovy calls to the components responsible for building the UI at runtime. The result is a simple but powerful syntax.

##### Common parameters

These following parameters are common and can be used for all input fields.

Parameter | Type | Required | Example | Description
--- | --- | --- | --- | ---
jcrPath | `string` |  | `jcrPath=/node/exo:title` | The relative path inside the current node.
mixintype | `string` with the commas (,) character. |  | `mixintype=mix:i18n` `mixintype=mix:votable,mix:commentable,mix:i18n` | The list of mixin types you want to initialize when creating the content.
validate | `string` with the comma (,) character |  | `validate=empty` `validate=empty,name` `validate=org.exoplatform.webui.form.validator.StringLengthValidator` | The list of validators you want to apply to the input. Possible values are: name, email, number, empty, null, datetime, length OR validator classes.
editable | `string` |  | `editable=if-null` | The input will be editable only if the value of this parameter is `if-null` and the value of this input is null or blank.
multiValues | `boolean` |  | `multiValues=true` | Show a multi-valued component if true and must be used only with corresponding multi-valued properties. The default value of this parameter is false.
visible | `boolean` |  | `visible=true` | The input is visible if this value is true.
options | `String` separated by the commas (,) character. |  | A list of parameters which are input while the content templates are initialized. | `"options=toolbar:CompleteWCM,height:'410px',noSanitization"`

      uicomponent.addCalendarField("publishedDate", fieldPublishedDate) ;

    %>

##### Upload Field

- Additional parameters

See also: Common parameters

- Example

When you create an upload form, you can store an image by two main ways:

- If you want to store the image as a property, use the following code:

    <%

      String[] fieldMedia = ["jcrPath=/node/exo:image"] ;

      uicomponent.addUploadField("media", fieldMedia) ;

    %>

- If you want to store the image as a node, use the following code:

    <%

      String[] hiddenField1 = ["jcrPath=/node/exo:image", "nodetype=nt:resource", "visible=false"] ;

      String[] hiddenField2 = ["jcrPath=/node/exo:image/jcr:encoding", "visible=false", "UTF-8"] ;

      String[] hiddenField3 = ["jcrPath=/node/exo:image/jcr:lastModified", "visible=false"] ;

      uicomponent.addHiddenField("hiddenInput1", hiddenField1) ;

      uicomponent.addHiddenField("hiddenInput2", hiddenField2) ;

      uicomponent.addHiddenField("hiddenInput3", hiddenField3) ;

      String[] fieldMedia = ["jcrPath=/node/exo:image"] ;

      uicomponent.addUploadField("media", fieldMedia) ;

    %>

- But, this code is not complete. If you want to display the upload field, the image must be blank, otherwise you can display the image and an action enables you to remove it. You can do as follows:

    <%

        def image = "image";

        // If you're trying to edit the document

        if(uicomponent.isEditing()) {

            def curNode = uicomponent.getNode();

            // If the image existed

            if (curNode.hasNode("exo:image")) {

                def imageNode = curNode.getNode("exo:image") ;

                // If the image existed and available

                if (imageNode.getProperty("jcr:data").getStream().available() > 0 && (uicomponent.findComponentById(image) == null)) {

                    def imgSrc = uicomponent.getImage(curNode, "exo:image");

                    def actionLink = uicomponent.event("RemoveData", "/exo:image");

                    %>

                        <div>

                            <img src="$imgSrc" width="100px" height="80px"/>

                            <a href="$actionLink">

                                <img src="/eXoResources/skin/DefaultSkin/background/Blank.gif" alt="" class="ActionIcon Remove16x16Icon"/>

                            </a>

                        </div>

                    <%

                } else {

                    String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;

                    uicomponent.addUploadField(image, fieldImage) ;

                }

            } else {

                    String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;

                    uicomponent.addUploadField(image, fieldImage) ;

            }

        }  else if(uicomponent.dataRemoved()) {

            String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;

            uicomponent.addUploadField(image, fieldImage) ;

        } else {

            String[] fieldImage = ["jcrPath=/node/exo:image/jcr:data"] ;

            uicomponent.addUploadField(image, fieldImage) ;

        }

    %>

    %>

##### Mixin Field

- Additional parameters

See also: Common parameters

type | `string` | The type of interceptor: `prev` or `post`.

- Example

    <%

      uicomponent.addInterceptor("ecm-explorer/interceptor/PreNodeSaveInterceptor.groovy", "prev");

    %>

##### How to add a new ECM template with tabs

To avoid refreshing the first tab for every action execution, add a new private function to the template with tabs. In the template, you must insert a new piece of code like the following:

    private String getDisplayTab(String selectedTab) {

      if ((uicomponent.getSelectedTab() == null && selectedTab.equals("mainWebcontent"))

                || selectedTab.equals(uicomponent.getSelectedTab())) {

            return "display:block";

        }

        return "display:none";

    }

    private String getSelectedTab(String selectedTab) {

        if (getDisplayTab(selectedTab).equals("display:block")) {

            return "SelectedTab";

        }

        return "NormalTab";

    }

Changing in every event of onClick must be done like the following:

    <div class="UITab NormalTabStyle">
      <div class="<%=getSelectedTab("mainWebcontent")%>
        ">
        <div class="LeftTab">
          <div class="RightTab">
            <div class="MiddleTab" onClick="<%=uicomponent.event("ChangeTab", "mainWebcontent")%>"><%=_ctx.appRes("WebContent.dialog.label.MainContent")%></div>
          </div>
        </div>
      </div>
    </div>

    <div class="UITab NormalTabStyle">
      <div class="<%=getSelectedTab("illustrationWebcontent")%>
        ">
        <div class="LeftTab">
          <div class="RightTab">
            <div class="MiddleTab" onClick="<%=uicomponent.event("ChangeTab", "illustrationWebcontent")%>"><%=_ctx.appRes("WebContent.dialog.label.Illustration")%></div>
          </div>
        </div>
      </div>
    </div>

    <div class="UITab NormalTabStyle">
      <div class="<%= getSelectedTab("contentCSSWebcontent")%>
        ">
        <div class="LeftTab">
          <div class="RightTab">
            <div class="MiddleTab" onClick="<%=uicomponent.event("ChangeTab", "contentCSSWebcontent")%>"><%=_ctx.appRes("WebContent.dialog.label.Advanced")%></div>
          </div>
        </div>
      </div>
    </div>

Finally, to display the selected tab, simply add it to the style of UITabContent class.

    <div class="UITabContent" style="<%=getDisplayTab("mainWebcontent")%>">

##### How to prevent XSS attacks

In the content management sytem, its typical feature is enabling JavaScript in a content. This causes the XSS (Cross-site Scripting) attacks to the content displayed in the HTML format.

However, there is no solution to keep JavaScript and to prevent the XSS attacks at the same time, so eXo Content allows you to decide whether JavaScript is allowed to run on a field of the content template or not by using the `option` parameter.

- To allow JavaScript to execute, add "`options = noSanitization`" to the dialog template file. Normally, this file is named `dialog1.gtmpl`.

- For example: The following code shows how to enable JavaScript in the Main Content field of the Free Layout Wecontent content:

    String [] htmlArguments = ["jcrPath = / node / default.html / JCR: content / JCR: data", "options = toolbar: CompleteWCM, height: '410px ', noSanitization" htmlContent];

- By default, there is no "`options = noSanitization`" parameter in the dialog template file and this helps you prevent the XSS attacks. When end-users input JavaScript into a content, the JavaScript is automatically deleted when the content is saved.

#### View

The following is an sample code of the View template of a content node:

- Get a content node to display:

    <%

      def node = uicomponent.getNode() ;

      def originalNode = uicomponent.getOriginalNode()

    %>

- Display the name of the content node:

    <%=node.getName()%>

- Display the exo:title property of the content node:

    <%

      if(node.hasProperty("exo:title")) {

    %>

      <%=node.getProperty("exo:title").getString()%>

    <%

      }

    %>

- Display the exo:date property of the content node in a desired format. For example: "MM DD YYYY" or "YYYY MM DD".

    <%

      import java.text.SimpleDateFormat ;

      SimpleDateFormat dateFormat = new SimpleDateFormat() ;

    %>

    ...

    <%

      if(node.hasProperty("exo:date")) {

        dateFormat.applyPattern("MMMMM dd yyyy") ;

    %>

        <%=dateFormat.format(node.getProperty("exo:date").getDate().getTime())%>

    <%

      }

    %>

- Display the translation of the Sample.view.label.node-name message in different lanaguages.

    <%=_ctx.appRes("Sample.view.label.node-name")%>

### List of Contents

#### Content List Template

The Content List Template allows you to view the content list with various templates. eXo Platform supports the following content list templates:

Template | Description
--- | ---
BigHotNewsTemplateCLV.gtmpl | Display contents under one column with a content list. The illustration of each content is displayed above the content.
ContentListViewerDefault.gtmpl | Its function is similar to BigHotNewsTemplateCLV.gtmpl. The illustration of each content is bigger.
DocumentsTemplate.gtmpl | Display contents under a content list with a NodeType icon or the illustration on the left of the corresponding content.
EventsTemplateCLV.gtmpl | Its function is similar to BigHotNewsTemplateCLV.gtmpl, but the illustration of each content is smaller.
OneColumnCLVTemplate.gtmpl | Display contents under one column. The illustration of each content is displayed on its left.
TwoColumnsCLVTemplate.gtmpl | Display contents under two columns. The illustration of each content is displayed on its left.
UIContentListPresentationBigImage.gtmpl | Its function is similar to BigHotNewsTemplateCLV.gtmpl, but the illustration of each content is bigger than the image displayed with ContentListViewerDefault.gtmpl and the text font is different.
UIContentListPresentationDefault.gtmpl | Its function is similar to BigHotNewsTemplateCLV.gtmpl, but the illustration of each content is smaller and the text font is different.
UIContentListPresentationSmall.gtmpl | Display contents under one column with a content list. The images are displayed on the left of the corresponding content and smaller than the images of the other templates.

#### Category Navigation Template

The Category Navigation Template displays all contents under the categories.

Template | Description
--- | ---
CategoryList.gtmpl | Display categories as a navigation bar.
CategoryTree.gtmpl | Display categories as a tree.
TagsCloud.gtmpl | Display all tags of the contents.

## WCM Explorer

### CSS

- By using WCM, all the stylesheets of each site can be managed online easily. You do not need to access the file system to modify and wait until the server has been restarted. For the structure, each site has its own CSS folder which can contain one or more CSS files. These CSS files have the data, and the priority. If they have the same CSS definition, the higher priority will be applied. You can also disable some of them to make sure the disabled style will no longer be applied into the site.

- For example, a WCM demo package has two sites by default: ACME and Classic. The Classic site has a CSS folder which contains a CSS file called DefaultStylesheet. Most of the stylesheets of this site are defined within this stylesheet. Moreover, the ACME site has two CSS files called BlueStylesheet and GreenStylesheet. The blue one is enabled and the green one is disabled by default. All you need to test is to disable the blue one (by editing it and setting Available to 'false') and enable the green one. Now, back to the homepage and see the magic.

### Note

Remember the cache and refresh the browser first if you do not see any changes. Normally, this is the main reason why the new style is not applied.

### CKEditor

Basically, if you want to add a rich text area to your dialogs, you can use the addRichtextField method. However, in case you want to add the rich text editor manually, you first need to use the addTextAreaField method and some additional Javascripts as shown below:

    <%

        String[] fieldDescription = ["jcrPath=/node/exo:description"] ;

        uicomponent.addTextAreaField("description", fieldDescription)

    %>

    <script>

      var instances = CKEDITOR.instances['description'];

      if (instances) instances.destroy(true);

      CKEDITOR.replace('description', {

        toolbar : 'CompleteWCM',

        uiColor : '#9AB8F3'

      });

    </script>

### REST Services

#### Overview

REST-style architectures consist of clients and servers. Clients initiate requests to servers; servers process requests and return appropriate responses. Requests and responses are built around the transfer of "representations" of "resources". A resource can be essentially any coherent and meaningful concept that may be addressed. A representation of a resource is typically a document that captures the current or intended state of a resource.

At any particular time, a client can either be in transition between application states or "at rest". A client in a REST state is able to interact with its users, but creates no load and consumes no per-client storage on the set of servers or on the network.

The client begins sending requests when it is ready to make the transition to a new state. While one or more requests are outstanding, the client is considered to be in transition. The representation of each application state contains links that may be used the next time, the client chooses to initiate a new state transition.

REST is initially described in the context of HTTP, but is not limited to that protocol. RESTful architectures can be based on other Application Layer protocols if they already provide a rich and uniform vocabulary for applications based on the transfer of meaningful representational state. RESTful applications maximize the use of the pre-existing, well-defined interface and other built-in capabilities provided by the chosen network protocol, and minimize the addition of new application-specific features on its top.

#### Restful Web Service

##### HTTP Methods

Here is the convention you should follow:

Method | Definition
--- | ---
GET | Get a Resource. Its state should not be modified.
POST | Create a Resource (or anything that does not fit elsewhere).
PUT | Update a Resource.
DELETE | Delete a Resource.

##### Formats

The followings are formats which need to be supported for all your APIs:

- JSON: This format makes developers easy to parse in a lot of languages, such as JavaScript, Python or Ruby.

- XML: Most of Java developers like using this format.

- ATOM: This is a standard format which can be used by many applications.

##### Data Format

The default format is JSON.

The response format can be specified by a parameter in the request: "format". You need to specify the format requested.

##### REST configuration

First, you need to register the REST service class to the configuration file in the package named conf.portal.

    <configuration xmlns="http://www.exoplaform.org/xml/ns/kernel_1_1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.exoplaform.org/xml/ns/kernel_1_1.xsd http://www.exoplaform.org/xml/ns/kernel_1_1.xsd">

      <component>

        <type>org.exoplatform.services.ecm.publication.REST.presentation.document.publication.PublicationGetDocumentRESTService</type>

      </component>

    </configuration>

##### Create a REST service

You can start creating GetEditedDocumentRESTService that implements from the ResourceContainer interface as follows:

    @Path("/presentation/document/edit/")

    public class GetEditedDocumentRESTService implements ResourceContainer {

        @Path("/{repository}/")

            @GET

            public Response getLastEditedDoc(@PathParam("repository") String repository,

               @QueryParam("showItems") String showItems) throws Exception {

               ........

            }

    }

Parameters | Definition
--- | ---
@Path("/presentation/document/edit/") | Specify the URI path which a resource or class method will serve requests for.
@PathParam("repository") | Bind the value repository of a URI parameter or a path segment containing the template parameter to a resource method parameter, resource class field, or resource class bean property.
@QueryParam("showItems") | Bind the value showItems of a HTTP query parameter to a resource method parameter, resource class field, or resource class bean property.

### UI Extensions

This part describes how to create a sample UI extension.

#### Overview

In eXo Content, it is possible to extend the Content Explorer and the ECM Administration with the UI Extension Framework. Indeed, you can add your own action buttons to the Content Explorer and/or add your own managers to the ECM Administration.

#### How to add your own tab in ECM Administration

##### Add your own UIAction

To add your own UIAction, do as follows:

1. Create a pom.xml file with the following content:

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

2. Create the src/main/java directory and start launching mvn eclipse:eclipse. Then, you can launch your eclipse and import this new project.

3. Create a new class called org.exoplatform.wcm.component.cache.UIWCMCacheComponent that extends org.exoplatform.ecm.webui.component.admin.manager.UIAbstractManagerComponent.

##### Add your own ActionListener

With the Webui framework, you will be notified if any given action is triggered. You just need to call your own action listener ($ACTIONNAME) ActionListener. For example, to create your own action listener for CacheView, do as follows:

1. Call CacheViewActionListener.

2. Add a static inner class called CacheViewActionListener that extends org.exoplatform.ecm.webui.component.admin.listener.UIECMAdminControlPanelActionListener.

You will see the expected code below:

    public class CacheViewComponent extends UIAbstractManagerComponent {

            public static class CacheViewActionListener extends UIECMAdminControlPanelActionListener

    <UIWCMCacheComponent>{

        public void processEvent(Event

        <UIWCMCacheComponent>event) throws Exception {

            UIECMAdminPortlet portlet = event.getSource().getAncestorOfType(UIECMAdminPortlet.class);

            UIECMAdminWorkingArea uiWorkingArea = portlet.getChild(UIECMAdminWorkingArea.class);

            uiWorkingArea.setChild(UIWCMCachePanel.class) ;

            event.getRequestContext().addUIComponentToUpdateByAjax(uiWorkingArea);

            }

            }

            }

3. Create the src/main/java directory and launch mvn eclipse:eclipse. You can then launch your eclipse and import this new project.

4. Create a new configuration file called conf/portal/configuration.xml to register your action (see Register your UI Action) with the org.exoplatform.webui.ext.UIExtensionManager service.

##### Register your UI Action

To register your UI Action, do as follows:

1. Create the code:

    <configuration xmlns="http://www.exoplaform.org/xml/ns/kernel_1_1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.exoplaform.org/xml/ns/kernel_1_1.xsd http://www.exoplaform.org/xml/ns/kernel_1_1.xsd">

            </component-plugin>

        </external-component-plugins>

    </configuration>

### Note

With this configuration, only the users with the *:/platform/administrators membership have the right to access the CacheView item.

2. Launch mvn clean install.

3. Copy the resource bundle.

### Note

All resources can be located in the src/main/resource package because the resources (*.xml, images, conf file) and the code are separated. This is very useful in a hierarchical structure.

Create ExamplePortlet_en.xml with the following content and add it to the src/main/resource package:

    <bundle>

        <!-- ################################################################################ # org.exoplatform.wcm.component.cache.UIWCMCacheForm

      # ################################################################################ -->

        <UIWCMCacheForm>

            <action>

                <Cancel>Cancel</Cancel>

                <Save>Save</Save>

                <Clear>Clear the cache</Clear>

            </action>

            <label>

                <maxsize>Max size :</maxsize>

                <livetime>Live time in sec :</livetime>

                <isCacheEnable>Cache enabled(should always be on production enviroment)</isCacheEnable>

                <hit>Hit count :</hit>

                <currentSize>Current size</currentSize>

                <miss>Miss count :</miss>

            </label>

        </UIWCMCacheForm>

        <!-- ################################################################################ # org.exoplatform.wcm.manager.cache.UIWCMCacheManagerForm

      # ################################################################################ -->

        <UIWCMCacheManagerForm>

            <action>

                <Cancel>Cancel</Cancel>

                <Save>Save</Save>

                <Clear>Clear the cache</Clear>

            </action>

            <label>

                <cacheModify>Cache to modify :</cacheModify>

                <maxsize>Max size :</maxsize>

                <livetime>Live time in sec :</livetime>

                <isCacheEnable>Cache enabled(should always be on production enviroment)</isCacheEnable>

                <hit>Hit count :</hit>

                <currentSize>Current size</currentSize>

                <miss>Miss count :</miss>

            </label>

        </UIWCMCacheManagerForm>

        <UIECMAdminControlPanel>

            <tab>

                <label>

                    <GlobalAdministration>Global Administration</GlobalAdministration>

                </label>

            </tab>

            <label>

                <UIWCMCache>WCM Cache</UIWCMCache>

                <UIWCMCachePanel>WCM Cache Administration</UIWCMCachePanel>

                <UIWCMCacheManager>Managing Caches</UIWCMCacheManager>

                <UIWCMCacheManagerPanel>WCM Cache Management</UIWCMCacheManagerPanel>

            </label>

        </UIECMAdminControlPanel>

    </bundle>

You must add the following content to configuration.xml to register the resource bundle.

### Note

By being added this configuration, the resource bundle has been completely separated from the original system. This is clearly useful for you to get an independent plugin.

    <external-component-plugins>

        <!-- The full qualified name of the ResourceBundleService -->

        <target-component>org.exoplatform.services.resources.ResourceBundleService</target-component>

        <component-plugin>

            <!-- The name of the plugin -->

            <name>ResourceBundle Plugin</name>

            <!-- The name of the method to call on the ResourceBundleService in order to register the ResourceBundles -->

            <set-method>addResourceBundle</set-method>

            <!-- The full qualified name of the BaseResourceBundlePlugin -->

            <type>org.exoplatform.services.resources.impl.BaseResourceBundlePlugin</type>

            <init-params>

                <values-param>

                    <name>init.resources</name>

                    <description>Store the following resources into the db for the first launch</description>

                    <value>locale.portlet.cache.ExamplePortlet</value>

                </values-param>

                <values-param>

                    <name>portal.resource.names</name>

                    <description>The properties files of the portal , those file will be merged

                        into one ResoruceBundle properties

                    </description>

                    <value>locale.portlet.cache.ExamplePortlet</value>

                </values-param>

            </init-params>

        </component-plugin>

    </external-component-plugins>

##### Run your own UI extension sample

Do as follows:

1. Run Tomcat.

2. Sign in as "root".

3. Go to the ECM Administration. You will see that a new extension has been already added to ECM Administrator.

### Authoring Extension

Publication add-ons for eXo Content.

#### Extended Publication Plugin

##### States

This extended publication has new states and new profiles that are enabled in eXo Content.

- Profiles

  - Author: This profile can edit a content and mark this content as redacted.

  - Approver: This profile approves a pending content (marked by the Author).

  - Publisher: This profile publishes contents or marks them as "Ready for publication" in multi-server mode.

  - Archiver: An administrative profile which moves contents to an archive storage.

- States

  - enrolled: It is a pure technical state, generally used for content creation.

  - draft (Author): Content is in editing phase.

  - pending (Author): The author validates the content.

  - approved (Approver): A content is approved by the manager.

  - inreview (Manager): This state can be used when a second approval state is needed (for i18 translation for example).

  - staged (Publisher): A content is ready for publication (multi-server mode).

  - published (Publisher or Automatic): A content is published and visible in the Live mode.

  - unpublished (Publisher or Automatic): A content is not visible in the Live mode.

  - obsolete: A content can still be published but it is not in an editing lifecycle anymore.

  - archived (Automatic): A content is archived and ready to be moved in the archive workspace if enabled.

##### Start/End publication dates

In most cases, you do not want to publish a content directly, but at a defined date and you can also want the content to be unpublished automatically after that. New properties are added to the new publication plugin, that allows you to manage this:

- publication:startPublishedDate_

- publication:endPublishedDate_

The eXo Content rendering engine does not know anything about publication dates, so another service needs to manage that. When the publisher sets start/end publication dates, he can "stage" the content. The content will go automatically to the "published" state when the start date arrives and to the "unpublished" state after end date. A cron job checks every hour (or less) all contents which need to be published (the start date in the past and the "staged" state) or unpublished (the end date in the past and the "published" state).

Thus, the publication dates are not mandatory and a content can go to:

- Staged: in multi-server mode, the publisher can only put the content to the "staged" state and wait for auto-publication.

- Published: in single-server mode, the publisher can directly publish a content (with or without publication dates).

##### New Publication Mixin

    <nodeType hasOrderableChildNodes="false" isMixin="true" name="publication:authoringPublication" primaryItemName="">

      <supertypes>

        <supertype>publication:stateAndVersionBasedPublication</supertype>

      </supertypes>

      <propertyDefinitions>

        <propertyDefinition autoCreated="false" mandatory="true" multiple="false" name="publication:startPublishedDate" onParentVersion="IGNORE" protected="false" requiredType="Date">

          <valueConstraints/>

        </propertyDefinition>

        <propertyDefinition autoCreated="false" mandatory="true" multiple="false" name="publication:endPublishedDate" onParentVersion="IGNORE" protected="false" requiredType="Date">

          <valueConstraints/>

        </propertyDefinition>

      </propertyDefinitions>

    </nodeType>

Publication plugin UI:

Note that some labels containing special or non-ASCII characters could not be well displayed in the publication UI. You can extend the width of the current UI State button by adding:

    .UIPublicationPanel .StatusTable .ActiveStatus {
      width: 75px !important;
    }

Also, for the publication date inputs, UIPublicationPanel should not initialize the dates to any default value. The publishing and unpublish CRON jobs will do this:

- A staged document with null publication start date is published instantly.

- A document with null publication end date is published forever.

See the export section for more information about the CRON jobs.

#### Publication Manager

The Publication Manager manages lifecycles and contexts in the eXo Content platform. It allows to manages different lifecycles based on different publication plugin in the platform.

    public interface PublicationManager {

        public List<Lifecycle> getLifecycles();

        public List<Context> getContexts();

        public Context getContext(String name);

        public Lifecycle getLifecycle(String name);

        public List<Lifecycle> getLifecyclesFromUser(String remoteUser, String state);

    }

In which:

- getLifecycles: returns a list of lifecycles (see below), with lifecycle name, publication plugin involved and possible states.

- getContexts: returns a list of context, with name, related Lifecycle and other properties (see below).

- getContext: returns a context by its name.

- getLifecycle: returns a lifecycle by its name.

- getLifecycleFromUser: returns a list of lifecycles in which the user has rights (based on membership property).

##### Lifecycle

A lifecycle is defined by a simple vertical workflow with steps (states) and profiles (membership). Each lifecycle is related to a Publication plugin (compliant with the JBPM or Bonita business processes).

For example: Two lifecycles with/without states

    <external-component-plugins>

        <target-component>org.exoplatform.services.wcm.publication.PublicationManager</target-component>

In the last example, there are three lifecycles:

- Lifecycle 1: Based on StatesAndVersionsPublicationPlugin .

  - This allows to be backward compliant with older eXo Content releases. If all your site contents are using an existing plugin, you can create a lifecycle for it and it will work.

  - For new instances, you should use the new plugin with dynamic states capabilities.

- Lifecycle 2: Based on AuthoringPublicationPlugin .

  - Visibility: Define only the "visible" steps. In this example, there is no step for "enrolled". Even if this step exists, it will not be displayed in the UI.

  - Automatic: Set a step as "automatic". In this mode, the step will be visible in the UI but it will be managed by the system (e.g. a cron job).

- Lifecycle 3: Simulates the StatesAndVersionsPublicationPlugin plugin. Note that this simple lifecycle will work in a single server configuration.

###### Listen to a lifecycle

When a state is changed, you can broadcast an event to add features. The event could look like this:

    listenerService.broadcast(AuthoringPlugin.POST_UPDATE_STATE_EVENT, null, node);

Listener declaration could look like this:

    <external-component-plugins>

      <target-component>org.exoplatform.services.listener.ListenerService</target-component>

      <component-plugin>

        <name>PublicationService.event.postUpdateState</name>

        <set-method>addListener</set-method>

        <type>org.exoplatform.services.wcm.publication.listener.post.PostUpdateStateEventListener</type>

        <description>this listener will be called every time a content changes its current state</description>

      </component-plugin>

    </external-component-plugins>

##### Context

A context is defined by simple rules. In eXo Content, you can select to enroll the content in a specific lifecycle (for example, publication plugin) based on context parameters. There are three parameters used to define contexts:

- Remote User: The current user who can create/edit the content.

- Current site name: The site from where the content is created (not the storage but the navigation).

- Node: The node which you want to enroll.

From these parameters, you can easily connect and define contexts based on:

- Membership: Does the current user have this membership?

- Site: On this particular site, you want to enroll contents in a specific lifecycle.

- Path: You can enroll contents in the lifecycles based on their path (from the Node).

- Type of content: You can enroll contents in the lifecycles based on their nodetype (from the Node).

Because each site has a content storage (categories + physical storage), you can select the right lifecycle for the right storage/site. To avoid conflicts on contexts, you can set a priority (the less is the best).

The logic is very simple. When creating a content, it should be attached a lifecycle with the lifecyle priority:

- context4 is the most important (priority=50): you will enroll the content in the lifecycle "lifecycle4" if:

  - The content creator has the manager:/company/finances membership.

  - The content is stored in repository:collaboration:/documents/company/finances or any subfolders.

  - The content is a '`exo:article`'.

- If not, you will continue with context3.

The logic is very simple. When you create a content, go lifecycle by lifecycle starting with the better priority:

- context4 is the most important (priority=50): you will enroll the content in the lifecycle "lifecycle4" if:

  - The content creator has the manager:/company/finances membership.

  - The content is stored in 'repository:collaboration:/documents/company/finances or any subfolders.

  - The content is a exo:article_.

- If not, you will continue with context3.

### Note

The contexts will be used only when the content is created and when you want to enroll it in a lifecycle for the first time. Once you have the corresponding lifecycle, you will set the lifecycle inside the content (see New Authoring Mixin) and the context service will not be called again for this content.

##### New Authoring Mixin

    <nodeType hasOrderableChildNodes="false" isMixin="true" name="publication:authoring" primaryItemName="">

      <propertyDefinitions>

        <propertyDefinition autoCreated="false" mandatory="false" multiple="false" name="publication:lastUser" onParentVersion="IGNORE" protected="false" requiredType="String">

          <valueConstraints/>

        </propertyDefinition>

        <propertyDefinition autoCreated="false" mandatory="false" multiple="false" name="publication:lifecycle" onParentVersion="IGNORE" protected="false" requiredType="String">

          <valueConstraints/>

        </propertyDefinition>

      </propertyDefinitions>

    </nodeType>

When adding the content in a lifecycle, set the publication:lifecycle_ property with the corresponding lifecycle.

### Note

A content can be in one lifecycle only.

Each time you change from one state to another, set the user who changed the state in publication:lastUser.

Querying based on publication status:

By adding this mixin to contents, you can access contents by simple queries based on the current user profile. For example:

- All your draft contents:

  - query: select * from nt:base_ where `publication:currentState`"draft" and `publication:lastUser`="benjamin".

- All the contents you have to approve.

  - call: PublicationManager.getLifecycles('benjamin','approved') => returns lifecycles where you can go to the 'approved' state.

  - query: select * from nt:base_ where publication:currentState="pending" and publication:lifecycle="lifecycle1" or publication:lifecycle="lifecycle3".

- All the content that will be published tomorrow.

  - query: select * from nt:base_ where publication:currentState="staged" and publication:startPublishedDate_="xxxx".

## FAQ

### How to deploy a workflow?

The addPlugin() function of WorkflowServiceContainer service is used to register a Business Process when a workflow is implemented. Thus, if you want to use a workflow, you are required to configure the workflow service to invoke the addPlugin() function by adding the external-component-plugins element to the configuration file.

You have to set values for the name and location of the workflow which you want to use. There are two ways to configure the location of the workflow.

#### Deploy a workflow inside a .war file

You can use "war:(FOLDER_PATH)" to configure which .jar files contain your workflow processes inside the .war file.

    <external-component-plugins>

      <target-component>org.exoplatform.services.workflow.WorkflowServiceContainer</target-component>

      <component-plugin>

        <name>deploy.predefined.processes</name>

        <set-method>addPlugin</set-method>

        <type>org.exoplatform.services.workflow.PredefinedProcessesPlugin</type>

        <init-params>

          <object-param>

            <name>predefined.processes</name>

            <description>load of default business processes</description>

            <object type="org.exoplatform.services.workflow.ProcessesConfig">

              <field name="processLocation">

                <string>war:/conf/bp</string>

              </field>

              <field name="predefinedProcess">

                <collection type="java.util.HashSet">

                  <value>

                    <string>/exo-ecms-ext-workflow-bp-jbpm-content-2.1.1.jar</string>

                  </value>

                  <value>

                    <string>/exo-ecms-ext-workflow-bp-jbpm-payraise-2.1.1.jar</string>

                  </value>

                  <value>

                    <string>/exo-ecms-ext-workflow-bp-jbpm-holiday-2.1.1.jar</string>

                  </value>

                </collection>

              </field>

            </object>

          </object-param>

        </init-params>

      </component-plugin>

    </external-component-plugins>

#### Deploy a workflow inside a .jar file

You can use classpath: to configure which .jar files contain your workflow processes inside the .jar file.

    <external-component-plugins>

      <target-component>org.exoplatform.services.workflow.WorkflowServiceContainer</target-component>

      <component-plugin>

        <name>deploy.predefined.processes</name>

        <set-method>addPlugin</set-method>

        <type>org.exoplatform.services.workflow.PredefinedProcessesPlugin</type>

        <init-params>

          <object-param>

            <name>predefined.processes</name>

            <description>load of default business processes</description>

            <object type="org.exoplatform.services.workflow.ProcessesConfig">

              <field name="processLocation">

                <string>classpath:</string>

              </field>

              <field name="predefinedProcess">

                <collection type="java.util.HashSet">

                  <value>

                    <string>/exo-ecms-ext-workflow-bp-jbpm-content-myworkflow.jar</string>

                  </value>

                </collection>

              </field>

            </object>

          </object-param>

        </init-params>

      </component-plugin>

    </external-component-plugins>

The notification message is displayed when you deploy a workflow on Jboss. If you use classpath: to register, you must put your workflow in the .jar files inside the gatein.ear/lib folder (instead of the lib folder) to make it work.
