The answer to pretty much everything you've asked for the moment
is "unknown". Are you receiving any errors? Can you post the code in
question?

I can't seem to figure out how saving and loading works:
I've implemented - (NSData *)dataRepresentationOfType:(NSString *)
type;
However, when I do a "save as?", the correct NSTextView's content
gets written out (rtf form), but my dataRepresentationOfType isn't
called. I haven't implemented writeToFile or the wrapper function.
- Where might Cocoa be getting the text from (how does it know
WHICH NSTextView to grab from)?
- How do I get it to call my NSDocument (custom)
dataRepresentationOfType?
For reading, I want a double click to launch my app and create a
new document; however, while a double click DOES launch my app (or
brings an already launched one forward), nothing else happens. I
have set the "document type" to my custom document (MyNSDocument),
but that doesn't get called (or the loadDataRepresentation: isn't
called)?
If I do an open, loadDataRepresentation DOES get called.
- What do I need to do to get a new document?
I've done this without problems on other programs, but I've done
(or failed to set) something that I can't figure out?
Thanks for an suggestions,
Mark
