Yes, you are correct in that assumption, sorry about the confusion.
Do you know how to mark an entities create methods as 'Required', leaving
the rest as 'Supports'?
I still think that there is something wrong with jboss's tx handling.
Originally I was creating these beans from a stateless session, with a
method that was marked as 'Required'. It created two beans that were marked
as 'Supports' and still no rows were inserted when using the minerva
datasource. When I switched to the oracle datasource it looked like each
bean was created within different (or non-existant) transactions, since the
second bean failed with a fk constraint, which should not have happened if
they were both inserted in the same transaction.
