EntityNotFoundException lors d'un merge

Bonjour,

je suis un peu perdu et j'ai besoin d'une aide extérieur. J'ai des soucis pour mapper une classe d'association avec des attributs.
Le mapping en lui-même, j'ai trouver des solution sur le net.
Par contre pour le merge en cascade, j'ai constemment des exceptions.

Est-ce possible? comment?

Dans mon cas, je cherche à persister un "travelRequest" avec sa liste de "requestMember".

Concrétement, lorsque je lance ceci :

Code:

1

@Test
  public final void testAddingTravelWithMember(){
    TravelRequest travelRequest = new TravelRequest();
 
    RequestMember requestMember = new RequestMember();
    requestMember.setTravelRequest(travelRequest);
    requestMember.setMember(member);
 
    travelRequest.getRequestMembers().add(requestMember);
    member.getRequestMembers().add(requestMember);
 
    travelRequest = emTest.update(travelRequest);
    Assert.assertNotNull(travelRequest.getTravelRequestId());
  }

j'obtiens l'erreur suivante :

Code:
