title: respond_with redirect with notice flash message not working
body: <p>I am using rails 3.0.7. In the controller I have:</p>
  
  <pre><code>  def create
      @subscription = Subscription\
        .new_from_nested_attributes_parameters(params[:subscription])
  
      if @subscription.save
        flash[:notice] = 'The Subscription was successfully created.'
      end
  
      respond_with @subscription
    end
  </code></pre>
  
  <p>and in the view:</p>
  
  <pre><code>&lt;%="Notice:#{flash[:notice]}"%&gt;
  </code></pre>
  
  <p>Doesn't print anything despite that the object is being properly saved.</p>
  
  <p>Do you have an idea on how should I fix this?</p>
