To simply test if the document really get's closed implement the close method in your NSDocument subclass. If it get's called, your document will be closed.
- (void)close {
[super close];
}
This should get called, if you do not have anything else interfering implemented (eg. canCloseDocumentWithDelegate). Stack trace for this call is in my case
-[MPDocument close] at **/MPDocument.m:200
