Marek Novotny commented on JBSEAM-4827:
---------------------------------------
Hmm, just thinking why is there possible to produce NULL, this shouldn't be passed
away if there is no message in StatusMessage. Have you got a simple test case for that?
Thanks for reporting.
FacesMessages may trigger NPE in JSF code
-----------------------------------------
Key: JBSEAM-4827
URL: https://issues.jboss.org/browse/JBSEAM-4827
Project: Seam 2
Issue Type: Bug
Components: JSF Integration
Affects Versions: 2.2.2.Final
Reporter: Stephan Bublava
FacesMessages.beforeRenderResponse() passes the return value of
FacesMessages.toFacesMessage() to FacesContext.addMessage() without any checks.
The problem is that toFacesMessage() may return null and FacesContext.addMessage() does
not allow that. (See
