Hi Andrus
Here are my findings. I think point number three is the reason that
callbacks are not happening for me.
Question - Just to reconfirm - if I have configured the callbacks in my
modeler and I can see an abstract declaration for the callback in the
parent class, and overriding them in the sub class - it means I have
configured them correctly?
1) Class EntityResolver
public LifecycleCallbackRegistry getCallbackRegistry() {
if (callbackRegistry == null) {
initCallbacks();
}
return callbackRegistry;
}
*here callbackRegistry is Not null.*
2) Class LifeCycleCallBackEventHandler
void performCallbacks(Persistent object) {
Statement - if (!defaultListeners.isEmpty()
&&
!excludingDefaultListeners(object.getObjectId().getEntityName()))
*here is defaultListeners isEmpty condition is true.*
3) Class LifeCycleCallBackEventHandler
private void performCallbacks(Persistent object, Class<?>
callbackEntityClass) {
Statement - Collection<AbstractCallback> entityListeners =
listeners.get(key);
*here - entityListeners is null*
Cheers
Manish
