Hi,
I have 3 objects in Interface Builder: NSArrayController,
NSManagedObjectContext and object that is NSApp's delegate.
NSManagedObjectContext is using XML store as backend
NSArrayController is binded to NSManagedObjectContext
When application starts, on applicationFinishedLauncing
NSArrayController is empty. [nsarraycontroller fetch:] didnt help.
However, after a while, it has all data just fine....
What is the appropriate way to do smth once Managed Object Context
is loaded?
"smth" is to get count of certain objects on applic start

Perhaps thinking about this a different way would clarify things.
You don't "load a context". You create a context and use it to fetch
objects from the store (or merely to create objects if you're using
an in-memory store).
So, if you have some controllers that aren't ready yet, you can
simply instruct them to -fetch: ... this will force them to fetch
immediately, rather than waiting for a future cycle of the run loop.

What's a "smth"?
