Whenever used, we use the notification of model loaded, and at runtime change whatever values needed to be tweeked for the current project. Like changing table name, setting isAbstract (or not), playing with relationship, etc.
Here is a simple case where we define the isAbstract attribute on all the entities of a generic model :
first ... NSNotificationCenter.defaultCenter().addObserver(AProjectControlerClass.class, new NSSelector("modelLoadedNotification", new Class[] { NSNotification.class }), EOModelGroup.ModelAddedNotification, null);
and latter ... public static void modelLoadedNotification(final NSNotification notification) { NSLog.debug.appendln(AProjectControlerClass.class.getName() + " notificationModelCharge..."); EOModel model = (EOModel) notification.object(); if (model.name().equals("AGenericModel")) { NSArray entities = model.entities(); log.info(model); Enumeration enim = entities.objectEnumerator(); while (enim.hasMoreElements()) { EOEntity entity = (EOEntity) enim.nextElement(); log.info(entity); entity.setIsAbstractEntity(true); } } }

Name it GenericUser (or whatever) in the framework. Subclass GenericUser as User in the app model and add whatever you need. Done.
Great! It sounds like I'm on the right track.
So how does WO handle the table name? In the framework, the GenericUser entity will have a table name (and, implicitly, a DB connection). When subclassing/extending the object in the _application_, is the table name and connection in the _framework_ just ignored?
