I've got two responses to my original post. Thanks.

So I understand now that NSDocument subclasses should not implement the
the NSCoding protocol. I changed my doc subclass so that a
NSMutableArray holds all the data. And I removed the initWithCoder,
encodeWithCoder methods from my doc subclass. Now the doc subclass
dataRepresentationOfType invokes archivedDataWithRootObject with the
mutable array. I can save and open files now.

The encodeWithCoder still gets called twice for each of the objects in
the mutable array. I do not understand this. The initWithCoder gets
called once, this sounds correct.

Can anyone explain this?

Thanks.
John Weeks
