Hi Michael,
your assumptions are correct.
After em.persist(e); I get this exception if I specify CascadeType.PERSIST:

because id in referenced object has an annotation
@GeneratedValue(strategy=GenerationType.IDENTITY) and that is something I
cannot and don't want to change.
If I don't specify CascadeType.PERSIST, I get this error:
