UserImpl needs to implement serializable??
Hi,
I am trying to build a set of portlets that can start a JBPM process. However, as specific processes can only started by certain roles, I had to add a table that maps the roles and the JBPM Processes. However, when I run this query, it throws an NonSerializable exception saying that org.jboss.portal.identity.UserImpl needs to be serializable. Now I know that I could just change UserImpl to be serializable (yay open source), but I think this might be a symptom of a deeper problem. For the life of me however, I cannot seem to find out what it would be.
I am running JBoss Portal 2.4 on JBoss 4.0.4GA
Here is the stack trace:
