And again, why is this any different to any other binding? It's

In this case, though, if you're not binding through any other
object, why not just set it directly (setManagedObjectContext:)?
Ah, very good. When I saw that it was called a "binding" in
Interface Buildero I went into the Cocoa Bindings Reference looking
for a binding. In this case, there is none, and indeed as you
suggested the only way do it is by setting directly:
[arrayController setManagedObjectContext:xxx] ;
[arrayController setEntityName:yyy] ;
[arrayController prepareContent] ;
NSManagedObjectContext is not listed in the Cocoa Bindings
Reference [1]. Is this really a "binding", or is it something
else? The documentation for binding NSArrayController
'managedObjectContext' in [1] calls it "registered with".
It's not clear what this means.
Bindings are bindings.
Well, I would say that the code I entered above is not a binding
because it does not, and could not, invoke
bind:toObject:withKeyPath:options. However, the effect is indeed the
same and I guess it doesn't matter what we call it.
Thanks, mmalc. My programatically-instantiated array controller is
working with my moc now.
