I am developing on JBoss 4.0.1sp3 + JBoss Portal 2.2.1rc2 on OSX 10.4.5, and
I'm getting an error on display of a portal page. The exception indicates a
hibernate.NonUniqueResultException, but I really can't detect what I did to
cause this, as I haven't hooked up my own persistence layer yet. Also, I
removed the page instance in the AdminPortlet and redeployed, but to no avail.
I could really use some suggestions. Only one page blows up with the other 5
pages working fine with about 3-5 portlets per page.
