Are you taking about parent/child ObjectContexts? I see you're calling
commitChangesToParent not commitChanges. Does it work when you call
commitChanges instead?
Here's the code I have for the callbacks:
callbackRegistry =
runtime.getDataDomain().getEntityResolver().getCallbackRegistry();
callbackRegistry.addCallback(LifecycleEvent.PRE_UPDATE,
ICSDataObject.class, "willUpdate");
public void willUpdate() {
}
