EntityManager adds instead removes object???!!

[mladen.babic]

Hi,
I'm using Seam 2.0.0 and JBoss AS 4.2.1 GA. Problem occurs when I try to delete some objects, entitymanager adds new objects (without any orders) in database instead removes.
I have categories and products and they have properties. While adding category properties, products in category extends properties from category. Problem occurs when I try to delete new added property in product. Instead that remove object entitymanager added new with same date every time when I try to delete.But when I closed a session(logout) it works fine!?

After hours and hours trying to solve this problem, I lost my nerv :(

Best regards,

mb

Hard to tell without seeing the code. This is probably more of a persistence provider (hibernate?) question and will probably be ignored on the hibernate forums ;-)
