Hi!
And about the state of an object after you call
entityManager.persist(object) with Cayenne... can your offer any
insights?...I mean in what state is the object? NEW (as it should to be
consistent with Cayenne classic?) or COMMITTED? (to be consistent with JPA
as implemented by Hibernate)
Does it really need to be COMMITTED to be consistent with JPA? Or is this an
abstraction leak in JPA/Hibernate ?
Regards,
Francisco
