Leonardo Uribe commented on MYFACES-3867:
-----------------------------------------
Thanks for the description of the problem. That changes everything I have
thought about, but I'm glad we have discovered a dormant bug inside c:forEach
(I assume the probability of an user could find it again is pretty low).
It seems the state of one page is being leaked to the other page, probably
because the way how are you navigating. For example, if you have the same
UIViewRoot instance, this component will hold the same attributes, and in that
sense the same FaceletState object. So the component structure will change but
the associated FaceletState is not, causing the problem described.
The solution is do something in the navigation to reset FaceletState. I can
imagine a couple of solutions, but how are you doing the navigation? I would
like to check it out before anything else.
