Hi Andreas,
I assume you have more than one persistence context. In this case you have
to add the @PersistenceContext annotation to your onSuccess() method.
Otherwise the system doesn't know which persistence context it should use.
(The related code is in JpaInternalUtils.getEntityManager() and
in EntityManagerManagerImpl)
Hope that helps.
