If I trigger the delete method from an EJB than it's works as excpected. This is my "Bulk" delete method. @Override   public <T extends EditableIF> List<Long> makeTransient(List<T> editables){     try {       if (editables == null || editables.size() == 0) {         log.error("Nothing to delete");         return new ArrayList<>();       }       // Backup the current flushmode       FlushModeType flushModeBefore = em.getFlushMode();       em.setFlushMode(FlushModeType.COMMIT);       int i = 0;       // Save or update all editables and flush every 50 times       ArrayList<Long> ids = new ArrayList<>();       for (T eif : editables) {         em.remove(mergeIfNeeded(eif));         ids.add(eif.getId());         i++;         if (i % BULK_FLUSH_SIZE == 0) {           em.flush();         }       }       em.flush();       em.setFlushMode(flushModeBefore);       return ids;     } catch (HibernateException ex) {       throw new InfrastructureException(ex);     }   } The intent of this mehtod is that I wan't improve performance for big deletions. As I said, if I trigger this method from  an EJB then it works fine. But if I trigger this from an SessionScoped CDI bean then the database entries are not deleted. For tracking the behaviuour of hibernate I switch the loglevel of org.hibernate.event.internal.DefaultDeleteEventListener to TRACE and add a delete interceptor. The related logentires are shown below: 13:36:58,120 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting a persistent instance 13:36:58,135 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting [com.siemag.components.model.message.MessagePrototype#281280] 13:36:58,135 INFO  [com.siemag.components.server.updating.DomainInterceptor] (http-localhost-127.0.0.1-8080-4) Delete ID 281280 entity com.siemag.components.model.message.MessagePrototype@917079[Id=281280,name=CC011/1444,creationTime=Sun Jan 13 15:09:44 CET 2013] 13:36:58,135 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting a persistent instance 13:36:58,151 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting [com.siemag.components.model.message.MessagePrototype#281281] 13:36:58,151 INFO  [com.siemag.components.server.updating.DomainInterceptor] (http-localhost-127.0.0.1-8080-4) Delete ID 281281 entity com.siemag.components.model.message.MessagePrototype@1914f6[Id=281281,name=HBS/145,creationTime=Sun Jan 13 15:09:44 CET 2013] 13:36:58,634 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting a persistent instance 13:36:58,634 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting [com.siemag.components.model.message.MessagePrototype#281280] 13:36:58,634 INFO  [com.siemag.components.server.updating.DomainInterceptor] (http-localhost-127.0.0.1-8080-4) Delete ID 281280 entity com.siemag.components.model.message.MessagePrototype@adfa17[Id=281280,name=CC011/1444,creationTime=Sun Jan 13 15:09:44 CET 2013] 13:36:58,650 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting a persistent instance 13:36:58,650 TRACE [org.hibernate.event.internal.DefaultDeleteEventListener] (http-localhost-127.0.0.1-8080-4) Deleting [com.siemag.components.model.message.MessagePrototype#281281] 13:36:58,650 INFO  [com.siemag.components.server.updating.DomainInterceptor] (http-localhost-127.0.0.1-8080-4) Delete ID 281281 entity com.siemag.components.model.message.MessagePrototype@1616c73[Id=281281,name=HBS/145,creationTime=Sun Jan 13 15:09:44 CET 2013] The strange thing here is that hibernate recognize the delete action but it doesn't excecute a delete statement on the DB.
