Re: JSF 2.2 Exit Flow

[Leonardo Uribe]

Hi

You can do what you want creating a custom ViewHandler and overriding
createView(...) method  like this:

@Override
public UIViewRoot createView(FacesContext context, String viewId)
{
UIViewRoot root = super.createView(context, viewId);
if (root != null)
{
FlowHandler flowHandler =
context.getApplication().getFlowHandler();
if (flowHandler.isActive(context, ,  flow1) 
!viewId.startsWith(/flow1/))
{
Flow flow = flowHandler.getFlow(context, , flow1);
flowHandler.transition(context, flow, null, null, viewId);
}
}
return root;
}

The code just check when the flow is active and if the view belongs to the
flow. If the navigation goes out of the flow it send a trasition ending the
flow.

Really this topic is being discussed under the EG, see:

https://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-1253

Let's see what happen.

 hi geoffrey,

 just fyi (in addition to the answer from michael):
 that's one of the major use-cases we had for codi/deltaspike
 (grouped-)conversations.
 you can use a listener (or an observer for PreViewConfigNavigateEvent +
 custom view-config meta-data) which
 just calls (WindowContext#closeConversations in case of codi or
 GroupedConversationManager#closeConversations in case of deltaspike).

 gerhard

  Hi,
 
  as far as I know, this is currently not possible. JSF won't let you
  navigate to something that is not defined as a node in the current flow.
 I
  quickly talked to Ed Burns about this some time ago and he more or less
  confirmed that this is the case.
 
  Regards
  Michael

   I have an application that consists of a dropdown menu bar with many

  correctly, however, once I am inside a flow, I would like any click on a
  menu item to exit the current flow, and then start a new one.  There are
  dozens of menu items in the application, so I was wondering if there is
 any
  way to have the current flow automatically exit when a menu item is
 clicked
  without having to define a flow-return for each menu item?
 
  Thanks,
