Hello again;
Well, I ran some debugging and I determined that ALL I needed was an initial
save. After that, all the core data stores are up-to-date, and faults result
in actual fetched data.
So, although kind of kludgy, I accepted the "Initial Save" behavior à la
Garageband, where the user is required to save the document at the document's
creation. I resolved this by adding the following code to my
NSPersistentDocument subclass.
The code which results in the following behavior:
1) The main document window is displayed
2) The document ensures there is actually a persistent store backing the PSC.
If there is, then no further action.
3) If there is no persistent store, prompt the user to save the document. This
should only occur if the document has never been saved. If the document was
successfully saved, no further action.
4) If the document was not successfully saved, close the document.
Like I said, this seems to be below-par. But I'm willing to accept it unless
someone has a simpler/better implementation.
