What version are you using? Do you see anything in the logs about something not being serializable? The problem used to be that the DefaultComponentManager was not serializable so when the Servlet container put things into the Session and would fail to serialize, so then when you went to get it out, you'd get a null, and it would throw this error. I thought this had been fixed, though... Are you on 2.0 final?
