Seems like you're abusing NSPersistentDocument.
For a start, it seems likely you want to subclass it, not create an
instance of it. Most documents have some kind of transient state, or
method overrides, that require a subclass. It's prima facie possible
that your documents don't, so perhaps it's OK, but it's certainly
unusual.
Next, this is a non-standard -- and incorrect-looking -- way to create
a NSPersistentDocument. Is there a reason you're not using a
NSDocumentController method (such as
'openUntitledDocumentAndDisplay:error:') to create it?
Also, the file type you're specifying doesn't look likely. "SQLite"
looks like a store type, not a file type, and the store type isn't
specified this way.
Finally, you're turning the usual mechanism inside out by *first*
running the save panel yourself, then creating a new document, then
trying to save the document but *suppressing* the save panel that
would normally appear because the document is new. Is there a reason
for that?
