I have an issue with hibernates flushing and updating.

We have an entity named USER
as well, we are doing some audit tracking

To do our audit tracking, we have extended org.hibernate.event.def.DefaultFlushEntityEventListener

and then we have overridden

public void onFlushEntity(FlushEntityEvent event) throws HibernateException
{
if (event.getEntity() instanceof ChangeAuditable)
{
if (currentUser.get() != null)
{
ChangeAuditable ca = (ChangeAuditable) event.getEntity();
Integer id = currentUser.get().getUserId();
ca.setChangeUserId(id);
}
}
super.onFlushEntity(event);
}

we then make a call to updateUser(..................)

We do not want to set the field changeUserId if no actual changes were made to the user object, how and where could we check for this, we have tried dirtyCheck, but that throws a nullpointerexception.

Any help would be greatly appreciated.

Hi,
If I'm not terribly mistaken, using an interceptor is a simpler solution. Just create an interceptor that extends EmptyInterceptor, and override the onFlushDirty()-method. This is called only when an object has been changed. I believe the documentation has a good example here: http://www.hibernate.org/hib_docs/v3/re ... vents.html
