ForeignKeys$Nullifier thinks a detached proxy is attached if another object with the same identifier is associated with the persistence context ----------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-6982 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6982 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 3.5.1 Environment: Hibernate 3.5.1, IBM DB2 9.7 on Win7 and AIX 6.1 Reporter: Martin Keßler 1. Create a transient object A which has a many-to-one property of type B 2. Create a proxy of type B with identifier x via Session.load(B.class, x) 3. Set the B-property in A to B 4. Flush and clear the persistence context; the B-proxy is now detached 5. Read the B-entity with identifier x through a query; a new object with id=x is now in the persistence context 6. Persist the A-entity (Session.save) 7. ForeignKeys$Nullifier.isNullifiable is called with the B-proxy, and checks if the persistence context contains an entity with the id x 8. The persistence context actually contains such an entity, but it's not the proxy 9. Hibernate tries to initialize the detached proxy, leading to a LazyInitializationException -- This message is automatically generated by JIRA.
