Never mind, the "(Missing) KVO notification old and new values"
section on mmalc's Cocoa Bindings Examples and Hints confirmed that
this is a bug. It mentions that this won't be fixed for the forseeable
future... could someone elaborate as to why?

When I observe an NSArrayController's selectedIndexes key like so:
- (void)awakeFromNib {
[arrayController addObserver:self forKeyPath:@"selectionIndexes"
options:(NSKeyValueObservingOptionNew |
NSKeyValueObservingOptionOld) context:nil];
}
- (void)observeValueForKeyPath:(NSString *)keyPath
ofObject:(id)object
change:(NSDictionary *)change
context:(void *)context {
NSLog(@"change: %@", change);
}
I'm never seeing the old and new indexes. I always see output like:
2008-08-09 00:14:04.513 test[12498:10b] change: {
kind = 1;
new = <null>;
old = <null>;
}
[arrayController selectedIndexes] gives the correct new value. A
table view is bound to the array controller in a typical
configuration (selectedIndexes is bound to the array controller).
Any ideas?
