Christian Bauer commented on HHH-2439:
--------------------------------------

Sure it would be nice to have it in FlushMode.MANUAL as well, without auto-commit. I'm only worried about breaking stuff.

About the spec: It's not in there. The specification is very clear: persist() brings an entity instance into managed state, an entity instance has an assigned identifier value if it is in managed state. This is a guarantee we are already breaking with persist() and auto-commit. The spec does not mention anything about "assigned at flush-time". I opened a JIRA case a year ago about it and was told by Gavin that this is fine within the spec. But really, it's not there and I carefully avoided saying that in he book. If someone found a section in the spec that allows it, I need the number.

> Much like we do now in 3.2 for out of transaction operations, we should delay performing insertions for post-insert generators with FlushMode.isManualFlushMode
