Jeff, I'm not sure whether you intended this or not... "S" is already in use for "State". I don't know what Hibernate will do with the same value pointing at two different classes - probably one wins, one loses. Since SimState is a subclass of State, the resulting problems might be a little hard to puzzle out. Frankly, I'd just drop it, or write up a short JIRA ticket. This is in new code (checked in Aug 1) that may not be fully baked, and isn't yet advertised as a feature. -Ed Staub -Ed Staub View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075837#...
