Change org.hibernate.impl.SessionImpl.instantiate(EntityPersister , Serializable) to call persister.setIdentifier(...) if interceptor returns a non-null value -------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-6309 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6309 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.6.5 Reporter: Chris Webb org.hibernate.Interceptor.instantiate(String entityName, EntityMode entityMode, Serializable id) does not have any way of leveraging the EntityPersister to set the identifier so this should be done in SessionImpl.instantiate if the interceptor returns a non-null value by calling persister.setIdentifier(result, id, this). Here is the completed change: {code:title=org.hibernate.impl.SessionImpl.java|borderStyle=solid} public Object instantiate(EntityPersister persister, Serializable id) throws HibernateException { errorIfClosed(); checkTransactionSynchStatus(); Object result = interceptor.instantiate( persister.getEntityName(), entityMode, id ); if ( result == null ) { result = persister.instantiate( id, this ); } else { // Set the id for the object instantiated by the interceptor. persister.setIdentifier(result, id, this); } return result; } {code} -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
