When I save an entity, I got the following exception. Does anyone know how "Found two representations of same collection " exception occurs?
My flush mode is "COMMIT". And my Hibernate session won't close until HTTP session is closed, that is I use reconnect/disconnect to manage the transaction.
Code:
