There are several places where information messages should display but they do not. It's always the same problem
when messages are cueued but not displayed.

This problem is present only in example in EAP 5.0.0 CR3, the same example taken from community version of Seam (Seam_2_2) runs without any problems on JBoss AS bundled with EAP 5.0.0 CR3

case 1)
After clicking selectItemsLink a page displays where I choose items in many listboxes and drop-down menus, after filling them I click "Apply" button and a message "Successfully updated" should display. A message in server log appears:
09:59:28,185 INFO [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=null[severity=(INFO 0), summary=(Successfully updated), detail=(Successfully updated)]

case 2)
After clicking fileUpload a page displays where I can upload a photo. The upload works fine but again: the same message as before should display and it doesn't

case 3)
After clicking s:button-and-s:link a new page displays.
Then I click "Do action link" or "Do action button" and a message "A simple action was performed" should display. But a message in log appears:
09:57:18,241 INFO [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=null[severity=(INFO 0), summary=(A simple action was performed), detail=(A simple action was performed)]
I can also click "Add a parameter link" or "...button" and a message "Foo=bar" should show up. Instead, the same as before:
09:58:18,117 INFO [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=null[severity=(INFO 0), summary=(Foo = bar), detail=(Foo = bar)]
