custom formbuilders for client side validations

rails.validations.custom.formbuilders.js

// rails.validations.custom.formbuilder.js
// Assuming that your custom Formtastic FormBuilder class is called 'MyCustomFormBuilderClass'
clientSideValidations.formBuilders['MyCustomFormBuilderClass'] = {
  add: function(element, settings, message) {
    clientSideValidations.formBuilders['Formtastic::SemanticFormBuilder'].add(element, settings, message);
  },
  remove: function(element, settings, message) {
    clientSideValidations.formBuilders['Formtastic::SemanticFormBuilder'].remove(element, settings, message);
  }
}

After wondering why it did not work for a while, I did a s/formbuilders/formBuilders/ and was illuminated :-)

Updated :)

missed one :-)

in case anyone else winds up here, note that you'll need to change clientSideValidations to ClientSideValidations (uppercase). Other than that still seems to work.
