Hi all.

Fairly new to Spring. I'm making a project that does not use Spring Web Flow, but is using the new annotation style in Spring 2.5.

I have a form which I validate and, if there are errors, I go back into the form to fix them. The problem is that when I do so, the ugly browser pop-up asking to re-post the data comes up.

I've tried returning a redirect: url, but doing that loses all the error messages that come up from validation.

Is there an easy way to avoid this behavior?

Code:
@Controller
@RequestMapping("edit")
public class EditController {

   @RequestMapping(method=RequestMethod.GET)
   public String showPage(@RequestParam(value="start", required=false) Boolean start, HttpSession session, ModelMap map)
   {
      if (start != null && start)
         map.put("start", true);
      else
         map.put("start", false);
      return "edit";
   }

   @ModelAttribute("myObject")
   public Notification getObject(@RequestParam(value="start", required=false) Boolean start, HttpSession session)
   {
      if (start != null && start)
      {
         return new MyClass();
      }
      return (MyClass)session.getAttribute("myObject");
   }

   @RequestMapping(method=RequestMethod.POST)
   public String submit(HttpSession session, ModelMap map, @ModelAttribute("myObject") MyClass myObject,
         BindingResult result, SessionStatus status) {
      new MyValidator().validate(myObject, result);
      result.setNestedPath("");
      if (result.hasErrors())
      {
         map.put("myObject", myObject);
         return "redirect:edit";
      }
      session.setAttribute("myObject", myObject);
      status.setComplete();
      return "redirect:confirm";
   }     
}
