[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2756) PostLoadEventListener is triggered on not fully loaded entity

PostLoadEventListener is triggered on not fully loaded entity ------------------------------------------------------------- Key: HHH-2756 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2756 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.4.sp1 Reporter: Roman Pichlík Priority: Minor PostLoadEventListener is triggered, but entity is not fully loaded especially is not possible to operate on mapped collection because org.hibernate.LazyInitializationException: illegal access to loading collection is thrown. PostLoadEventListener should be triggered when is entity fully loaded. Let say, we have Parent, Child entity and PostLoadEventListener which iterates over child collection. public class Parent { private Set<Child> children; } public class PostLoadEventListener implements PostLoadEventListener { public void onPostLoad(PostLoadEvent event) { Parent parent = (Parent) event.getEntity(); for(Child child: parent.getChildren()){ // org.hibernate.LazyInitializationException: illegal access to loading collection System.out.println(child); } } } Fix tip: see org.hibernate.loader.Loader#initializeEntitiesAndCollections, if i understood well the key are following statements. if ( hydratedObjects!=null ) { int hydratedObjectsSize = hydratedObjects.size(); if ( log.isTraceEnabled() ) { log.trace( "total objects hydrated: " + hydratedObjectsSize ); } for ( int i = 0; i < hydratedObjectsSize; i++ ) { TwoPhaseLoad.initializeEntity( hydratedObjects.get(i), readOnly, session, pre, post ); //event is trigerred here } } //but collection are loaded by this code if ( collectionPersisters != null ) { for ( int i=0; i<collectionPersisters.length; i++ ) { if ( !collectionPersisters[i].isArray() ) { endCollectionLoad( resultSetId, session, collectionPersisters[i] ); } } } //post event handlers should be trigerred here
