If you have an IntegerField and you don't define it within the HTML form, when it is submitted and ChangeManipulator.save is called (I assume AddManipulator is the same here), and if the value is None, then it is submitted to the sql execute as a string and the sql writes it out as a string (i.e. some_number = , ...).
