Why does TopLink roll back transactions without displaying any error?

Question

I am trying to do bulk inserts via a stored procedure that takes in a VARRAY of varchars (complete insert statements). Becuase of integrity constraint, the stored procedure can only be executed after the parent record has been inserted via registerObject. I have created a new class that implements the SessionEventListener and put the logic to call the stored procedure under prepareUnitOfWork. I then put the listener in the event manager. The whole transaction would go through, but in the end TopLink would rollback the transaction for no apparent reason. I do not see any exceptions or errors, and from the database side my DBA has created a test_log table that will track the statements I passed in, and they all look fine. Has anyone encountered similar problems before?
