getEntityName() throws org.hibernate.TransientObjectException: proxy was not associated with the session
--------------------------------------------------------------------------------------------------------

                 Key: HHH-3230
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3230
             Project: Hibernate3
          Issue Type: Bug
          Components: core
    Affects Versions: 3.2.2
         Environment: Mac OS X, JDK 1.5
            Reporter: Howard M. Lewis Ship


I'm retrieving an entity that contains a OneToMany relationship.

The master entity is retrieved, within a transaction, via Session.get(Class,Serializable).

@Entity
public class MapUnitSurvey extends ActiveDO
{
       @ManyToOne(fetch = FetchType.LAZY)
    private VegetationType vegetationType;
}


@Entity
public class VegetationType extends AbstractEnum
{
}

ActiveDO and AbstractEnum are abstract base classes with @MappedSuperclass.

I retrieve the vegationType:

   VegetationType type = survey.getVegetationType();


Then I need the type's entity name

	String entityName = session.getEntityName(type);
			

This fails with the TransientObjectException.

Inspecting with the debugger, I see that type is a CGLIB-enhanced proxy, and that there's a fully initialized bean in the target field of the proxy.  I'll attach a screenshot of some debugging data.

In summary; the entity was retrieved via a lazy fetch, appears the be correct, seems to be in the session and yet the exception occurs.

I've tried to resolve this by re-fetching the object from the session, and a few other tries, with no luck.
