I have discussed with Ian about the patch for handling localized error messages in formencode. Basically you pass a "gettext" function in the state parameter, which then translates the message, This would allow the TG controller to pass the i18n gettext function to formencode. I haven't had time to check the formencode SVN yet, but ask Ian about it.
