Stuck with NSSortDescriptor

Hi there,

I've got an NSArrayController pointing to NSSortDescriptor in a custom class using the Model Key Path in the IN Bindings.


Here's the sort descriptor:

alphaSortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"artist" ascending:YES selector:@selector(caseInsensitiveCompare:)];


The same NSArrayController has its Model Key Path's contentArray set as:

@distinctUnionOfObjects.artist

and is working fine without  the descriptor.

However as soon as I link the NSSortDescriptor I get the following error message:

[NSSortDescriptor count]: selector not recognized [self = 0x396fd0] An uncaught exception was raised [NSSortDescriptor count]: selector not recognized [self = 0x396fd0] Uncaught exception: <NSInvalidArgumentException> *** - [NSSortDescriptor count]: selector not recognized [self = 0x396fd0]


Any help greatly appreciated.

Micha
