Hibernate collection n'est pas associée à une session

J'ai trouvé plusieurs questions et réponses relatives à cette question, mais ils semblent tous à couvrir l'une des principales causes du problème: l'extraction d'une collection en dehors d'une transaction ou dans une autre transaction. Mais dans mon cas, je suis aller chercher dans la même transaction lors de l'extraction d'un objet parent et de collection.

@Service
@Transactional
public class IntegrationServiceImpl implements IntegrationService {
@Override
    public Integration getIntegrationByIdFetchBackendParameters(Long integrationId) {
        Integration integration = integrationDao.get(integrationId);
        //not all integrations have to have backend.
        if (integration.getBackend() != null) {
            Hibernate.initialize(integration.getBackend().getBackendParameters());
        }
        return integration;
    }
...

Mais quand il s'agit de mettre en veille prolongée.initialiser cette branche dans org.mise en veille prolongée.collection.interne.AbstractPersistentCollection
est exécutée

if ( session == null ) {
                throw new HibernateException( "collection is not associated with any session" );
            }

Je ne peux pas voir pourquoi session est null. Quelqu'un pour expliquer ceci, et proposer une solution?
