no, validators work on a converted type - same type as the model object
notice your converter is converting the value to a codablevalue type -
that is the object that the validators will work on - they validate
the same object that will be put into the model if validation passes.
it looks like in your case your validation is a conversion-related
validation so that check should go into your converter - the
converttoobject() method - you can throw ConversionException and set
the appropriate error message on it.
