I have a document based Core Data app. MyDocument.nib contains an NSTableView bound to an NSArrayController. There also are "+" and "-" buttons, which send "add:" resp. "remove:" to the array controller.
SomeEntity.m (subclass of NSManagedObject) implements validateForInsert:, validateForUpdate: and validateForDelete: - none of which are ever called. Why? What I try to accomplish: SomeEntity has a property called "uniqueKey" and this is (no big surprise) meant to be unique. When the "UniqueKey" column in my table view gets edited, validateUniqueKey:error: gets called, I check the new value for uniqueness and all is fine. But hitting the "+" button several times inserts several objects with the same key (Default Value). What should I do? How to make validateForInsert: get called? 10.6.2. Kind regards, Gerriet. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
