Re: JSF 2.2 Exit Flow
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).

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

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,

Thanks, Geoff I was wondering how your code looked. Now I know via your post[1] in PrimeFaces forum. :) i'm not using Faces Flow yet, so I'm just listening/reading. :) [1] http://forum.primefaces.org/viewtopic.php?f=3t=35881
