i18n_multi_locales_validations facilitates multi-locales attributes validations. It's made to validates attributes from Globalize2 translations models.
How can I change i18n_multi_locales_validations and i18n_multi_locales_form to work with globalize2 v0.1.1 and Rails 2.3.8 and Rails 3? Globalize2 version v0.1.1 has change code in many places...
Your approach to add validations in globalize2 is very good and should be made forward.
