Exception in takeValue:forKey:

[David Wetzel]

Hi folks,

why is this raise there? I should only raise if the key is null as far as I can 
see.

- (void) takeValue: (id)anObject forKey: (NSString*)aKey
{
  SEL           sel = 0;
  const char    *type = 0;
  int           off;
  unsigned      size = [aKey length] * 8;
  char          key[size+1];

  GSOnceMLog(@"This method is deprecated, use -setValue:forKey:");
  if (anObject == nil)
    {
      [NSException raise: NSInvalidArgumentException
                  format: @"Attempt to set nil value for key '%@'", aKey];
    }
(.....)
