I have an NSDocument based app that supports two file types, one as an Editor
(for the new app version's documents) role and one as a Viewer (for old app
version documents). Both are based on the same document class which reads both
but saves only the new version format.
When -saveDocument: gets called on an old-version document, the framework
completely ignores that by role definition (Viewer), it can't save the format
and calls -saveToURL:ofType:::: with the old URL (wrong file extension) and old
type (can't save that).
I find it a little odd that something like this hasn't been sorted out long ago,
so naturally I'm wondering once more today, what am I doing wrong?
Regards
Markus
