When I delete an object and re-add new one with the same id (within the same session) I get NonUniqueObjectException. How can I tell hibernate to remove the deleted object from it’s cache or wherever the old object is kept.

try


or

But I also want to keep new added objects and as far as I know clear or evict would remove them as well.

If you call session.evict(yourobject) on your old deleted object,
then you keep the new added objects in persistence context.
Where's the problem?

Do I have to keep deleted objects in an array and when I add new object with the same id (key) then I evict it before I do saveOrUpdate?
(Just small explanation - I always delete all objects at the start, then I create and add new once – some of them might be genuinely new ones (different primary key) and some might be with the same primary key as the old one (the one that I just deleted - but they have not been removed from cache).
