From Apple's "Document-Based Applications Overview": If you ... don't want an error alert to be presented to the user, return an error object whose domain is NSCocoaErrorDomain and whose code is NSUserCancelledError. The Application Kit presents errors through the NSApplication implementations of the presentError: and presentError:modalForWindow:delegate:didPresentSelector:contextInfo: methods declared by NSResponder. Those implementations silently ignore errors whose domain is NSCocoaErrorDomain and whose code is NSUserCancelledError. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
