[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-273) refresh() throws entity not managed exception

refresh() throws entity not managed exception --------------------------------------------- Key: EJB-273 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-273 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.2.1 Reporter: Charles Canning Priority: Critical When you call EntityManager.refresh() to reattach an entity to the entitymanager, it throws: java.lang.IllegalArgumentException: Entity not managed at org.hibernate.ejb.AbstractEntityManagerImpl.refresh(AbstractEntityManagerImpl.java:260) The code is: public void refresh(Object entity) { checkTransactionNeeded(); //adjustFlushMode(); try { if ( ! getSession().contains( entity ) ) { throw new IllegalArgumentException( "Entity not managed" ); } getSession().refresh( entity ); } catch (MappingException e) { throw new IllegalArgumentException( e.getMessage(), e ); } catch (HibernateException he) { throwPersistenceException( he ); } } It is checking if the object is already in the session - this will not allow me to reattach. If I "cast" the EM to the session delegate, refresh works fine because it doesn't contain this check.
