exception handling causes facesmessages to not be shown
-------------------------------------------------------

                 Key: JBSEAM-3611
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3611
             Project: Seam
          Issue Type: Bug
          Components: Exception Handling
    Affects Versions: 2.0.2.SP1
         Environment: ubuntu hardy heron amd64,  firefox 3.0.3, jboss-4.2.0.GA_CP01, seam 2.0.2.SP1, richfaces 3.1.4.GA,
            Reporter: Ken Gullaksen
            Priority: Minor


When using ajax submit to an action method in a conversation scoped bean the following behavior is encountered.

On fresh deploy notloggedinexception message will be shown. If the page is refreshed and subsequently another action with @restrict annotation is called, the messages will not be displayed. There is no warning that facesmessages have been enqeud but not displayed, and another page refresh will cause the message to be shown. 

May be a richfaces bug. I tried with the latest release of richfaces(3.2.2.GA) with same problem.
