Basically, if you want to add a rich text area to your dialogs, you can use the [_addRichtextField_|#CONTref.InsideWCMTemplates.ContentTypes.Dialog.RichTextField] method. However, in case you want to add the rich text editor manually, you first need to use the [_addTextAreaField_|#CONTref.InsideWCMTemplates.ContentTypes.Dialog.TextAreaField] method and some additional Javascripts as shown below:

{code:groovy}
<%
	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>
{code}
