Ooops, that code fragment forgot a line:

           // Cast is safe as createBinder caused MyBindException to be use
           MyBindException myErrors = (MyBindException) errors;
           myErrors.removeErrors(myErrors.getFieldErrors("luhn"));     
// *********
           errors.rejectValue("luhn", "LUHN_INVALID", "2 A valid Luhn is 
required.");
