Rich Feit commented on BEEHIVE-827:
-----------------------------------
I'm still looking at this, and trying to figure out if there's any way to move
onCreate() inside the Faces request, or whether it's fishy to plug the
FacesContext factory in order to create the FacesContext earlier in the
request... or if either of these is really desirable. The issue here (which
you've probably already discerned) is that you're adding FAcesMessages to the
previous request's FacesContext.
One quick thing to note is that you can bind directly to page inputs from
pages, using an expression like "#{pageInput.myPageInput.someProperty}". I
think this issue is still worth exploring, but out of curiosity, would that
work for you?

> I created a FacesBackingBean that raises an action in the controller. The
> action returns a Forward sending the request back to the JSF. The forward
> generates an ActionOutput of a simple String message. In the onCreate()
> method of the FacesBackingBean I called getPageInput() to retrieve the
> ActionOutput. I then cast the output as a string and pass it to a new
> FacesMessage which is passed to FacesContext.getInstance().addMessage(). In
> the JSF, the message is not displayed using the <h:messages/> tag.
> If I add the new FacesMessage to FacesContext in an event handler that does
> not raise an action, the message is displayed as expected.
> If I add the new FacesMessage to FacesContext in onCreate() without going
> through an action, the statement throws a NPE.
> @Override
> protected void onCreate() throws Exception {
> FacesContext.getCurrentInstance().addMessage("foo", new
> FacesMessage("bar"));
