Re: EO Being Faulted After ERXEC.saveChanges

Hi Chuck:

Thanks for the pointer. Unfortunately I did not find any observation of 
the objectChanged… Notifications and no implementation of did(has)Saved 
methods. I experimented with the _objectsChangedInStore method in ERXEC. 
If I comment out the call to super._objectsChangedInStore everything 
works just fine. This is just weird. I also tried to use 
EOEditingContext instead of ERXEC, but that caused other issues. I don't 
know what else I can look at. Hmmmmmm.

	/**
	 * Overridden so add a bugfix from Lenny Marks
	 */
	@Override
	public void _objectsChangedInStore(NSNotification nsnotification) {
		ERXEnterpriseObject.FlushCachesProcessor.perform(this, (NSArray) 
nsnotification.userInfo().objectForKey("objects"));
		if (savingChanges) {
			synchronized (queuedNotifications) {
				queuedNotifications.addObject(nsnotification);
			}
		}
		else {
			System.out.println("2 _objectsChangedInStore: "+__updatedObjects);
			super._objectsChangedInStore(nsnotification);
			System.out.println("3 _objectsChangedInStore: "+__updatedObjects);
		}
	}

Here is my System.out log for the 2 statements above.
