[jboss-user] [JBoss Portal] - Null Layout when portlet maximized

Hello.  I have been tasked with upgrading our AS from jboss-4.0.3SP1 to jboss-4.0.5.GA, and our portal from 2.2.1-SP3 to 2.4.1.  Both the AS and portal where downloaded and unzipped manually.  My JDBC driver, jboss-portal.sar, and portal-hsqldb-ds.xml have been copied to the /server/default/lib.  At the moment I am only working with the hypersonic database.

Almost everything works at this point.  In addition to migrating my portlet descriptors I have been bringing our layout into compliance with JBoss standards - in the past we were not using many portlet styles and had no controls in the title bar.   I have my portlet decorations and contols  rendering correctly in my portlet title now and all of the controls work except for maximizing a portlet.

The exception:

  | 	org.jboss.portal.core.command.ControllerCommand.dispatch(ControllerCommand.java:84)

I have searched the forums and found a thread or two concerning this exception where the solution seemingly had to do with the database connectivity.  Since my entire portal is working except maximizing, I'm inclined to say I have a different problem.  That said, we've never tried maximizing our portlets before so it could be some old mistake made before I started.

Any thoughts?  Thanks in advance.
