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 _______________________________________________
