since it seems NSArrayController doesn't return the default 'YES' value for
all keys (is this documented, somewhere?). Still, no success. 

I think what you'd actually want here is:


+ (BOOL)automaticallyNotifiesObserversForKey:(NSString *)key;
{
    if ( [key isEqualToString:@"arrangedObjects"] ) {
        return YES;
    }
    return [super automaticallyNotifiesObserversForKey:key];
}


The problem is that the key you're dependent on (arrangedObjects) isn't firing notifications by default. If it was, you should get change notifications for infoString as well. So all you *should* need to do is to activate the key you're dependent on.


Haven't tested it, though.
