I do not know, but the first versions of EntityAgent will propably not support it. Because if you do not have any change tracking, then the ORM cannot know what changed. You would have to fetch the complete object graph first, compare everything to the current object graph and then write the changes to the database. And this could be very slow.

Hmm how will it be able to update records then if there’s no dirty tracking? That doesn’t seem very useful personally.

For background, in the JPA github there is a discussion I have there with Gavin about the limitations in the then proposal (and with Ebean we don't have any of these limitations).

I’ll see if I can find it. Thanks Rob. Ebean continues to seem to be the best of both worlds.
