NullPointerException if user quikcly decides to click a different link or button before the page renders -------------------------------------------------------------------------------------------------------- Key: JBSEAM-335 URL: http://jira.jboss.com/jira/browse/JBSEAM-335 Project: JBoss Seam Issue Type: Bug Environment: Seam 1.0.1.GA. JBoss 4.0.4, Windows XP, Facelets, MyFaces, Hibernate Reporter: Keith Naas When a user is on one of our screens, they can decide to click a link before the next page loads. Sometimes, when this do this quickly enough, it causes a NullPointerException in Manager.touchConversationStack at line 181. Somehow, the currentConversationEntry is null and it breaks when it executes getCurrentConversationEntry().touch(). I tried unsuccessfully to duplicate this scenario on the Hotel and DVD Store demos hosted on JBoss.
