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: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.2 Environment: Mac OS X, JDK 1.5 Reporter: Howard M. Lewis Ship Attachments: Debugging output from IDEA.jpg, NarrowingProxyTestCase.zip 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.
