NSWindowRestoration issue

Question

I am having a difficult time implementing this new "feature" of Mac OS X 10.7. For the most part, my application works without my having to do anything. Files reopen on launch as expected. If the file is deleted however, my application opens to nothing and a new, blank document needs to be opened via the File menu.

So, what I have done so far is when a new window is created, I call

[myWindow setRestorationClass:(Class < NSWindowRestoration >)self];

with self being my NSDocument class.

Since restoreWindowWithIdentifier:state:completionHandler: is a class method I can't call my windowController creation method [self makeWindowControllers] from within it nor could I call [self initWithType:error] to create a new document if the one being sent has been deleted. How does one tell if the document being sent has been deleted from within this method?

I've read all I can find on Apple's site and elsewhere on this issue and am getting nowhere. Realize my core understanding of this is lacking and I apologize for that. I appreciate any help. Thank you.

As far as I understand the problem I think you have to enable in your app delegate

- (BOOL)applicationShouldOpenUntitledFile:(NSApplication *)sender;
{
    return YES;
}

Did you try that?
