Hi Helge, It's not clear to me what the problem is with - 
setNilValueForKey:

The Apple documentation at http://developer.apple.com/documentation/ 
Cocoa/Reference/Foundation/Protocols/NSKeyValueCoding_Protocol/ 
Reference/Reference.html#//apple_ref/occ/instm/NSObject/ 
setNilValueForKey:
says that 'The default implementation raises an  
NSInvalidArgumentException'

Are you saying that the Apple implementation does not do what the  
documentation says?
