For what it's worth, I checked this

Seems so!

Correct. That's what I am expecting.

NSDocument ascertains this information from calling
-writableTypesForSav
Thanks very much for this info. I've been coding in Cocoa all year, but I'm
still a newbie to plenty of stuff, including this.
I have developed code that does permit me to append the file extension to the
filename:
- (IBAction) saveDocumentAs:(id)sender
{
NSSavePanel* theSavePanel = [[NSSav

You're not missing anyth
Thanks very much for your advice.
After receiving your email I set the filetype in the object's init method:
[self setFileType:FILEEXTENSION_QUICKLOOK]; //#define
FILEEXTENSION_QUICKLOOK @"CAQuickLook"
However, saving the file as before, still does not append a file extension.

Yes, this is the expected pattern with KVO. Contrary to what you might
think at first, it is *fast*.
To use OmniPlan 2 as an ex
I agree, it is certainly a valid and useful design pattern that I use as well.
But I just wasn't sure that it is needed in the OP's case. From the part that I
read (and I missed the first part of the thread), there was no mention of which
objects needed to be notified.

I'm coming late to this conversation, but couldn't you just add a -[MyObject

Why use notifications at all? Is it some other object that needs to be n

Well, I thought you were, but I still think the issue is in the way you're
