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). regards, gerhard http://www.irian.at Your JSF/JavaEE powerhouse - JavaEE Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2014/1/18 Michael Kurz > Hi, > > as far as I know, this is currently not possible.

Re: JSF 2.2 Exit Flow
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 Am 17.01.2014 02:10, schrieb Geoffrey Longo: I have an application that consists of a dropdown menu bar with many menu items. Each menu item will initiate a new faces flow. This is working 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, Geoff

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=3&t=35881
