Integration

Hello
I am using Tomlink JPA as persistence provider for EJB3.

The problem has raised when I tried to remove some entities from a collection. As I have some exprience in Hibernate, I thought all the details entities will be removed when I remove them from the collection but soon I realized that in TopLink this is not the case.

now I am removing the entities individually, but the problem is that it seems the entity manager has removed the entities I declared but in database all the records are exists!!!

More stranger, in next execution the deleted entities are not loaded and everything seems ok but if I restart the application server all the removed data is coming back!!

after removing the entity I called entityManager.flush() and even I put TransactionAttribute for the value of REQUIRES_NEW but nothing has changed.

would you please help me on this problem?

thanks
