If I understand Philip, I am having the same challenge, It isn't
enough for me to let NSPersistentDocument do the load, I want a
notification or some way of knowing after the load is completed so
that I can fix up other related stuff. Is there someway to at a
minimum:
1) In some overridden method of NSPersistentDocument subclass for my
document as an example:
- (void)windowControllerDidLoadNib:(NSWindowController
*)windowController
2) To test for when the nib loaded via the NSPersistentDocument's open
event or was it instead via the new document event.
I am new to all of this please be gentle and Philip was here first, If
I misread his question and mine is completely different?
Thanks in advance for any advice,
Richard

I'm using a Core Data model and letting NSPersistentDocument manage
the task of finding and loading the application's model. My model
contains data that I am displaying in a graph (SM2DGraphView) A
problem I'm having is that once the model data is done loading I
want to send a refresh message to the graph. So, I put the
refresh message at the end of the document's initWithType:error:
but this seems to be too early in the process and when the refresh
asks the NSArrayController bound to the data, it says it is empty,
that is, canRemove returns false.
I tried getting a notification with
NSManagedObjectContextObjectsDidChangeNotification but this didn't
seem to work. I can post the code in case this should have worked,
but first I wanted to ask if there might be a simpler approach?
Thanks,
Philip
