Description Richard Harms 2008-12-15 22:37:34 CST 
When running in a cluster and a .war is undeployed, the UserVisitStatus cannot be retrieved because on undeployment they were removed by calling the .ear on other nodes, but the UserVisit is still active in user's cookies. Perhaps fix by allowing allowing the UserVisit to come back to life?

Comment 1 Richard Harms 2008-12-29 22:40:52 CST 
There doesn't appear to be a fix for this currently. JBoss doesn't check to see if the war is still deployed on other nodes, and calls valueUnbound for all sessions, but leaves them in the session cache.
