-------------------------------------------------------------

                 Key: JBSEAM-1429
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1429
             Project: JBoss Seam
          Issue Type: Bug
    Affects Versions: 1.3.0.ALPHA
         Environment: Tomcat 6.0.13, jboss-seam-CVS.20070601


            Reporter: Przemyslaw Jaskierski


As described in http://www.jboss.com/index.html?module=bb&op=viewtopic&t=110606. After adding SeamFilter to filter chain I've got
this stacktrace after invoking an action from a4j:commandLink. As requested I'm going to attach example application.
