Keeping the list server busy while everyone else seem to have better things to do...
Is there an magic trick to get the framework to actually call NSDocument's
- (BOOL)canAsynchronouslyWriteToURL:(NSURL *)url ofType:(NSString *)typeName
forSaveOperation:(NSSaveOperationType)saveOperation
I'd like to do as the documentation suggests and put the document writing into a
background tread (if you follow the little flood of NSDocument related messages
you know why). Documentation says:
--------
The default implementation of this method returns NO. You are strongly
encouraged to override it and make it return YES, after making sure your
overrides of document writing methods can be safely invoked on a non-main
thread, and making sure that unblockUserInteraction is invoked at some
appropriate time during writing.
--------
There's no precondition listed, but there seems to be one as my override is
never called. Why?
Regards
Markus
