Hy, I found out the source of the Problem. It's because i am using my own EJB with own Hibernate Mapping Classes to write the User data. I reduced the cache-time of the portal, so the Portal-Objects expire, and as i thougt, it works. Is there any command to force a refresh of the Portal-Hibernate Objects, so that I don't have to reduce the cache-time in the ehcache.xml File?
