Is the form submitted twice?

Question

JavaScript

Rails 3.1.2, for some reason forms are submitted twice instead of once...

# _form.html.erb<br>
        <%= form_for @message, :remote => true do |f| %><br>
          <div><br>
            <%= f.hidden_field :user_id %><br>
          </div><br>
          <%= f.error_messages %><br>
          <div><br>
            <%= f.text_area :content %><br>
          </div><br>
          <div><br>
            <%= f.submit(@message.new_record? ? "Post" : "Update") %><br>
          </div><br>
        <% end %><br>
<br>
# messages_controller.rb<br>
...<br>
 def update<br>
    @message = Message.find(params[:id])<br>
    if @message.update_attributes(params[:message])<br>
      respond_to do |format|<br>
        format.html { redirect_to @message, :notice => "Successfully updated message." }<br>
        format.json { render :json => { :response => :ok, :id => @message.id }.to_json,<br>
                             :status => :ok }<br>
        format.js { render :js => "alert('ok!');" }<br>
      end<br>
    else<br>
      format.html { render edit_message_path }<br>
      format.json { render :json => { :response => :error }.to_json,<br>
                           :status => :error }<br>
      format.js { render :js => "alert('fail!');" }<br>
    end<br>
  end<br>
...<br>

Maybe jquery or jquery_ujs is loaded 2 times, look through firebug or chrome dev tools.
