What does your components.xml look like?

| @PersistenceContext(unitName="boIcomsSecurityAudit", type=PersistenceContextType.EXTENDED)

By the wiring in your components.xml

It's like an Extended PC that is scoped to a conversation rather than a SFSB. It has significantly simpler propagation rules
anonymous wrote : must you use SMPC or can you use JPA Extended PersistenceContext as follows?
You can use either, but you must use Hibernate atm.
