Class FlowExecutionRedirect

java.lang.Object
  org.springframework.webflow.execution.ViewSelection
      org.springframework.webflow.execution.support.FlowExecutionRedirect

All Implemented Interfaces:

java.io.Serializable

public final class FlowExecutionRedirect
extends ViewSelection

Concrete response type that refreshes an application view by redirecting to an existing, active Spring Web Flow execution at a unique SWF-specific flow execution URL. This enables the triggering of post-redirect-get semantics from within an active flow execution.

Once the redirect response is issued a new request is initiated by the browser targeted at the flow execution URL. The URL is stabally refreshable (and bookmarkable) while the conversation remains active, safely triggering a ViewState.refresh(org.springframework.webflow.execution.RequestContext) on each access.
