Reverting a Core Data document is tricky. Apple's recommended methods are given here: http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/NSPersistentDocumentTutorial/04_Department/department.html#//apple_ref/doc/uid/TP40002832-SW6 But you should also read these: http://www.cocoabuilder.com/archive/cocoa/161579-bug-in-nspersistentdocument-tutorial.html#161579 http://www.cocoabuilder.com/archive/cocoa/174292-bug-nspersistentdocument-core-data-tutorial.html#174292 http://www.cocoabuilder.com/archive/cocoa/177523-bug-nspersistentdocument-core-data-tutorial.html#177523 Since "Revert" is not a major advertised feature of the app I was working on, after trying unsuccessfully to make it work for an hour or so, I gave up and implemented Revert to simply close and re-open the document. It's a little slow and ugly, but it works, and eliminates a branch of regression possibilities. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
