| Hallo All,
I have a view-based OutlineView with one column bound to an TreeController (arrangedObjects) and the TableViewCell bound to objectValue.name. The TreeController is bound to the managedObjectContext.
Nearly everything is fine. With the Add-Button a new line will be added with the default Value of my entity attributes. And with the Add Child Button a child will be added. The Remove-Butten removes the selected row.
The only problem is, that I can’t save the values. The Save-Action in the AppDelegate is bound to the Save-Item of the File-Menu. If I tab cmd+s the file menu in the titlebar becomes blue.
And the NSLog() I placed in the SaveAction shows that the action is called and no errors occur.
- (IBAction)saveAction:(id)sender { if (![[self managedObjectContext] commitEditing]) { NSLog(@"%@:%@ unable to commit editing before saving", [self class], NSStringFromSelector(_cmd)); }
NSError *error = nil; if ([[self managedObjectContext] hasChanges] && ![[self managedObjectContext] save:&error]) { [[NSApplication sharedApplication] presentError:error]; }
NSLog(@"Save?"); }
But nothing will be saved.
Many thanks for your help!
Kind regards, Raycord |
