Multilingual easyform issues

After adding the behavior to the collective.easyform content type, I made this simple test:

  • create a easyform (with no options other than a title)
  • translate this easyform
  • use the form (it should send an email to the Plone site owner)
  • switch language: the translated form is submitted without any other intervention!

The problem:
after the form is submitted, there's a redirection to the form view, but the language switching button have still all the form data...

How to inform the language switcher to use the correct redirected link (with no data)?

Generally, is collective.easyform multilingual friendly?

Another issue:
A translated form is using its own storage, so the registration plugin cannot work with a multilingual form.
