add this to your subclass:

- (id)reversedSortDescriptor
{
NSLog(@"reversed...");
id r = [super reversedSortDescriptor];
return [[[[self class] alloc] initWithKey:[r key] ascending:[r ascending] selector:[r selector]] autorelease];
}

and see if that helps.

Hi,

I made a little demo app [1] to isolate the problem I'm having with sort descriptors dissapearing from NSArrayControllers after those have been resorted (see previous mail in this thread). The program is self-explanatory - you'll see how the array controller's sort descriptor first is an instance of ThingyController and then magically an instance of NSSortDescriptor. I'd appreciate any help.

Cheers,
Knud
