[eclipselink-users] JPA flush and identity/serial columns
|
If I am using GenerationType.IDENTITY, then must I flush() any time I make use of the just-allocated identifier?
In the case of saving an object graph, will EclipseLink do this for me? I am seeing (as a counterexample) that Hibernate 3.5 won't. That is, if I persist a new object (which won't have an identifier until a trip to the database has been made), and then in the same transaction set a @ManyToOne relationship to point to it, should it be the case that the JPA provider should take care of sequencing these database operations? I would think so.
We're seeing a situation which may prove to be the last straw in our adoption of Hibernate that seems to indicate that this kind of sequencing is not occurring. Before I laboriously switch over to EclipseLink I want to make sure this isn't a specification thing.
Best,
Laird
