I'll check out the Postgres definitions.
I am having problems with boolean CMP EJB attributes. These do not map nicely to Postgres BOOLEAN or BIT columns, causing errors when the DB is accessed :-( The advice I have seen on the JBoss forums suggests that using java.lang.Boolean instead of straight boolean fixes the problem. Would it be a problem to do that change in Nukes?
The enable/disable function worked, and the BOOLEAN/BIT issue for Postgres seems to be resolved.
