Thanks. This looks useful.
Do you do something similar with the DB connection? I've now got a
model in my framework and a model in my application. Some of the
entities in the framework are generic and can optionally be subclassed
(User); others are unlikely to be subclassed (UserLogEntry).
How do I tell the framework that its entities should be accessed via
the connection in the model in my application rather than the one in
the framework's own model?
And if a method in the framework fetches and returns an entity, how
would it know to return the subclass of the entity defined in the
application rather than the generic entity in the framework? (This
question probably shows my confusion... I'm sure I'm just thinking
about this problem wrong!)

Whenever used, we use the notification of model loaded, and at

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);
}
}
}

And what about adding additional relationships specific to the
application to the User entity?
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?
