Hi everyone, I'm trying to resolve a very strange problem. In my document I have implemented willPresentError:, and on Lion when someone opens a locked document and tries to edit it, an error is produced, which I forward to super, which gives people the option of unlocking, canceling, or duplicating.
If they choose to duplicate, I get another call to willPresentError, but this time the supposed error is not an NSError at all, but instead an NSDocumentErrorRecoveryAttempter object.
I have no idea how this could happen, and the stack trace doesn't seem to help. Any ideas where to look?
