browny browny commented on JBSEAM-4652:
---------------------------------------
I have traced the error to the facescontext returning a null for the
viewId...And i see another JIRA post for it
https://jira.jboss.org/browse/JBSEAM-4639 . I debuged it and found the JSF
facescontext.viewroot returning a null viewId for postback.
