[hibernate-issues] [Hibernate-JIRA] Created: (EJB-221) TransientObjectException with FetchType.LAZY on @ManyToOne and field access on target entity

[Christian Bauer (JIRA)]

TransientObjectException with FetchType.LAZY on @ManyToOne and field access on target entity
--------------------------------------------------------------------------------------------

         Key: EJB-221
         URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-221
     Project: Hibernate Entity Manager
        Type: Bug

  Components: EntityManager  
    Reporter: Christian Bauer
    Priority: Blocker
 Attachments: fetchtest.jar

Latest SVN of everything:

        em = factory.createEntityManager();
        em.getTransaction().begin();

        Soldier2 soldier = em.find(Soldier2.class, mickey.getId());
        System.out.println("### TRYING TO ACCESS PROXY ID...");

        // This triggers a SELECT, it shouldn't
        System.out.println("### PROXY ID : " + soldier.getTroop().getId());

        // This throws a TransientObjectException
        em.flush();

The @ManyToOne troop in Soldier2.java has only FetchType.LAZY, the CascadeType.PERSIST is removed. 

I expect the problem to be in CascadingAction PERSIST_ON_FLUSH.noCascade() somewhere, apparently the proxy has no Id anymore during flush-time and is considered transient (how can a proxy be transient?).

The problems appear as soon as I move the annotations from getters to fields in Troop2.java.

The attached tests are for HEM.
