                </table>
            </form>
        </spring:nestedPath>

in the above code, i would like to bind only 3 items to my modelAttribute( issue_id, deve_names and priority)
but the jsp page is not getting displayed and its showing the following error:

" Neither BindingResult nor plain target object for bean name 'developer_Issues' as request attribute "

my controller code:

    @RequestMapping(value = "/issue/PMIssueDetails", method = RequestMethod.POST)
    protected ModelAndView onSubmit(@ModelAttribute Developer_Issues developer_Issues, BindingResult result, SessionStatus status, HttpServletRequest request) throws Exception {
        System.out.println("got the values into PMIssueDetails from PMISsueDetails.jsp");
        System.out.println("Developer_issue.getIssueId = " + developer_Issues.getIssue_id());
        ModelAndView mv = new ModelAndView("/issue/PMIssueDetails");
        return mv;
    }

my dao class..
