Hi,

I'm upgrading to Seam 2.0 and included jars (Hibernate EntityManager 3.3.1.GA, etc).

I have some code that used to work OK but now I'm getting the stack attached (when running integration tests in the embedded container).

If I have a Parent with a Set of children and I delete one of those children (that is set to cascade) this works OK. As soon as I call flush after the update manually I get the stack.

@Stateless
@Remote(ContractManager.class)
@Local(ContractManagerLocal.class)
@Name("contractManager")
public class ContractManagerBean implements ContractManager {
...
 public Contract updateContract(Contract contract) {
 contract = em.merge(contract);
 // Add this line I get a stack... remove and it's OK
 em.flush();
 return contract;
 }

I need to control the flushing in my case in a more complicated example due to database constraints.

Any advise ?
