EJB3 delete problem with detached entities
------------------------------------------
Key: EJB-350
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-350
Project: Hibernate Entity Manager
Issue Type: Bug
Components: EntityManager
Affects Versions: 3.3.1.GA
Environment: hibernate-3.2.5.ga, hibernate-entitymanager-3.3.1.GA, MS SQL Server,
Windows XP Profesisonal
Reporter: Balwinder Sodhi
Trying to remove a detached entity fails with the exception given below. Looking into the
source code at EJB3DeleteEventListener.java:45 I find that the method (pasted below)
*always* throws the exception at line#45 regardless of the event contents.
@Override
protected void performDetachedEntityDeletionCheck(DeleteEvent event) {
EventSource source = event.getSession();
String entityName = event.getEntityName();
EntityPersister persister = source.getEntityPersister( entityName, event.getObject() );
Serializable id = persister.getIdentifier( event.getObject(), source.getEntityMode()
);
entityName = entityName == null ? source.guessEntityName( event.getObject() ) :
entityName;
throw new IllegalArgumentException("Removing a detached instance "+ entityName
+ "#" + id);
}
java.lang.IllegalArgumentException: Removing a detached instance com.xxx.em.Edition#282
