In this case I dont't see how this could work, because I have to define
'some_name' in the SQL-Method's Attributes and supply a default value in
case the user does not supply a value for 'some _name' in the form that
feeds the SQL-Method. Therefor sone_name is never blank and the optional
never is true.
Am I missing something?
