I would like to implement undo/redo for a model object which in turn is also a ivar backed property of a document object. I'm already using the document's undo manager to undo/redo setting the model object property. Once the property is set, the application has features to change properties of the model object. I'm not sure how to implement undo/redo for the changes of the model object's properties and ivars. -- Luc Van Bogaert _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
