Ah, I did not foresee this.
I really can't generally recommend calling -saveToURL:::error: instead of
saveToURL:::completionHandler: because the latter does some important things
that the former doesn't. Unfortunately, I think the problem you're seeing with
the hang is insurmountable without ad

OK, I'm back. Had to fork my project since Block_copy()/release() is not
available in 10.5 SDK. But it works now. See code below.

What Ken said.
Also, it might be more convenient to use NSBlockOperation or
-addOperationWithBlock so the function parameters (including the completion
handler) are all captured correctly for you automatically. It's a lot more
convenient than stashing things in an NSDictionary.
Finally, I miss

Thank you, Kevin. I believe you and Jens on this. Indeed, when I close a
document window, its document receives a

AppKit-initiated autosaves generally happen for two main reasons: the autosave
timer, and file coordination. These are both initiated with
-autosaveWithImplicitCancellability:completionHandler:. The "implicitly

What do you mean by "break into" or "a sequence of operations"? The frameworks
are almost certainly not inter
With Auto Save enabled in a document, I find that Lion sometimes wants to break
into a sequence of operations to do an Auto Save. I haven't been able to find
any recommendation of how to tell Auto Save "No, I'm busy now". I just figured
out how to do it by overriding saveToURL.
