title: Flash Attributes are not working
body: <p>I have got an Spring MVC project (AppFuse) and Flash attributes are not transmitted to the GET request.</p>
  
  <p>What I do:
  In the transmitter method:</p>
  
  <pre><code>@RequestMapping(method = RequestMethod.POST)
  public String onSubmit(Entity entity, BindingResult errors, HttpServletRequest request, HttpServletResponse response, RedirectAttributes ra){
     ...
     ra.addFlashAttribute("id", entity.getId().toString());
     success = "redirect:somePage";
     ...
     return success;
  }
  </code></pre>
  
  <p>In the receiver method, I cannot get the passed flash attribute. I tried these approaches:</p>
  
  <ul>
  <li>by ModelMap</li>
  <li>by Model</li>
  <li>by @ModelAttribute("id")</li>
  </ul>
