Translations seem to be my greatest enemy:( I have a nice Formtastic form, and a yaml translation file. I've set the translation in the `config/application.rb` like this:

```
config.i18n.available_locales = :nl
config.i18n.default_locale = :nl

```

and a before\_filter method in `application_controller.rb` like this:

```
before_filter :set_locale

def set_locale
  session[:locale] = params[:locale] unless params[:locale].nil?
  I18n.locale = session[:locale] || I18n.default_locale
end

```

My form looks like this (it's written in haml):

```
= semantic_form_for Ad.new do |f|       
  .holder
    = f.inputs do
      = f.input :name

    = f.inputs do
      = f.input :reason

```

and finaly my nl.yml looks like this:

```
nl:
  formtastic:
    titles:
      ads:
        reason: "Waarom verkoop je het?"
    labels:
      ads:
        reason: "Waarom verkoop je het?"
    hints:
      ads:
        reason: "Waarom verkoop je het?"
    placeholders:
      ads:
        reason: "Waarom verkoop je het?"

```

As you can see I've added the same translation to all these keys Formtastic provides but none show up, the label remains `Reason` and there is no placeholder text. For as far as I can tell I've done exactly what the Formtastic readme prescribes. I'm using formtastic (2.2.1) with rails (3.2.8). If I add activerecord translations to the `nl.yml` the label does get translated. Why don't the formtastic translations work?
