Hi Dain, For what it's worth, this is how I do it in the MVCSoft Persistence Manager, and just have some special handling when moving state back and forth from the db. Of course, there are worms (consequences), but I think these are unavoidable. For instance, because you can not change the value of an entity primary key, you can not change the relationship participation of an entity with this mapping. Anyway, it doesn't seem like the spec gives a lot of options here. :-) -Dan > interesting database fk mappings are not supported in JBossCMP yet (like not > null foreign keys).
