    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 ?
