Very nice tutorial, thanks. One fix you should consider though is to make the selectionIndexes binding two-way. That is the way bindings like this are supposed to work. Bindings should always go from view to controller and from controller to data, never the other way around. That avoids infinite update loops and retain cycles. The way to do that is to add the following at the end of mouseUp:

NSDictionary *info = [self infoForBinding:@"selectionIndexes"];
[[info objectForKey:NSObservedObjectKey] setValue:[self selectionIndexes] forKeyPath:[info objectForKey:NSObservedKeyPathKey]];

Really great tutorial. This is a problem that I tried to work out a few weeks ago and decided to go on another route because it seemed better at the time. This tutorial might just make me have another go though. You rock.
