[ http://issues.apache.org/jira/browse/JS2-216?page=comments#action_59733 ] David Sean Taylor commented on JS2-216: ---------------------------------------
Yup Ive seen that one before, but ONLY when you try to access the portal before the servlet has completely loaded and initialized. I just ran a few adhoc tests with old nav state (_ns) URLs from expired sessions (including your URL) and it was handled gracefully. Could this be because you hit the portal before it was started? The demo version of J2 has quite a few webapps and takes time to get all loaded up depending on how fast your machine is > NPE when refreshing page after restart > -------------------------------------- > > Key: JS2-216 > URL: http://issues.apache.org/jira/browse/JS2-216 > Project: Jetspeed 2 > Type: Bug > Components: Deployment > Versions: 2.0-M1 > Environment: JDK 1.4, Windows XP, Tomcat 5 > Reporter: Howard M.
