Funny thing. I added the following method to my node entity:

- (NSSet *) children
{
    NSSet * tmpValue;

    [self willAccessValueForKey: @"children"];
    tmpValue = [self primitiveValueForKey: @"children"];
    [self didAccessValueForKey: @"children"];

    return tmpValue;
}

Similarly , I added the following to the leaf class:

- (NSSet *) children
{
    return nil;
}

And now, sorting works just fine.

Happy, but puzzled

Thanks for replying, Timothy.

Anyone managed to get a sorted outline view, preferably using bindings?

I have, but I don't think I can shed any light on your problem, since you appear to have tried, without success, the solution that works in my application. The tree controller is bound to sortDescriptors, and the NSTableColumn of the outline view has its value bound to the controller's arranged objects.
