[jboss-jira] [JBoss JIRA] Resolved: (JBPORTAL-1094) ClassCastException when casting SubSession to List in PortalSessionSynchronizationInterceptor

ClassCastException when casting SubSession to List in PortalSessionSynchronizationInterceptor --------------------------------------------------------------------------------------------- Key: JBPORTAL-1094 URL: http://jira.jboss.com/jira/browse/JBPORTAL-1094 Project: JBoss Portal Issue Type: Bug Security Level: Public(Everyone can see) Components: Portal Portlet Affects Versions: 2.4 Final, 2.6.Alpha1 Environment: Portal Clustered using both Portal-ha-2.4.1CR1 and 2.4.0-ha running on JBoss AS 4.0.4 Reporter: Poul Bildsoee Moeller Assigned To: Julien Viet Priority: Minor Fix For: 2.6.Beta1 In org.jboss.portal.portlet.aspects.portlet.PortalSessionSynchronizationInterceptor the following code is executed (code partially inserted): HttpSession session = req.getSession(false); if (session != null) { ss = (SubSession)session.getAttribute(key); } // try { // Set the sub session for the portlet synchronization if (ss != null && ss.isActivated()) { invocation.setAttribute("subsession", ss); } // invocation.invokeNext(); } finally { List modifications = (List)invocation.getAttribute("subsession"); The code sets the SubSession as an attribute on invocation and then later tries to fetch this again and at the same time cast to List. This doesn't work since SubSession isn't a List. I am not sure what is meant to happen so I cannot really fix the problem myself.
