I'd suggest you keep trying to find a way to avoid doing this. Even
inconveniences like having to work through an extra dialog before or after the
standard save panel might be preferable.
The problem is that the list of things that that the "default implementation"
of such methods has changed over time from 10.5-10.8. If you override one and
*don't* call super, then your app may inexplicably break in a future OS X.

You use the word "call", but that's not what you're supposed to do -- you need
to invoke a NSInvocation. Perhaps what you meant. If not, the process is
explained in these old release notes:

under this heading:
Advice for Overriders of Methods that Follow the

NSDocument implements this protocol already (though it's not documented as
doing so), so you simply need to send one of the 'commit…' methods to self, I
suppose. However, without an API contract beyond what you quoted, it's not
absolutely clear it's that simple.
