session bean lost values.

Hi,

I tried to use spring mvc 3.1 session scope to pass values from child page back to parent page (jsp), but the value is lost after refresh the parent page.

Here is my TestController code:

@Controller
public class TestController {

    private static final Logger logger = Logger.getLogger(TestController.class);

    @Autowired
    private CategorySessionBean categorySessionBean;


    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Model model) {
        logger.debug(" =======HOME PAGE========");
        model.addAttribute("categorySessionBean", categorySessionBean);
        return "index";
    }

    @RequestMapping(value = "/popupPage", method = RequestMethod.GET)
    public String popupPage(Model model) {
        logger.debug(" =======POPUP PAGE========");
        logger.debug(" =======categorySessionBean: ========"+categorySessionBean.toString()); // all fields in this session bean thave lost when child javascript refresh parent page.
        model.addAttribute("categorySessionBean", categorySessionBean);
        return "popupPage";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String processPopupPageSubmit(
        @ModelAttribute("categorySessionBean") CategorySessionBean categorySessionBean, BindingResult result, SessionStatus status) {
        logger.debug(" =======processSubmit========");
       logger.debug(" =======categorySessionBean: ========"+categorySessionBean.toString()); // after filled in the fields of this session bean in popupPage and click on submit, all values are store here.
        return "popupPage";
    }
}

parent jsp file (index.jsp):

Any suggestion is very appreciated.
