public String editApp(#PathVariable int id, ModelMap model) {
PIL_P_APPLCTN application = appService.findById(id);
logger.info("=========>"+application.getId()+" "+application.getAPPLCTN_CD());
List<PRM_CONTEXTE> cntxt = cntxtService.findAllOBJECTS();
model.addAttribute("cntxt", cntxt);
model.addAttribute("application", application);
model.addAttribute("edit", true);
model.addAttribute("loggedinuser", getFullName());
return "formApp";
}
#RequestMapping(value = { "/edtApp-{id}" }, method = RequestMethod.POST)
public String updateApp(#Valid #ModelAttribute("application") PIL_P_APPLCTN application, BindingResult result, ModelMap model,
#PathVariable int id) {
logger.info("====**=====>"+application.getId()+" "+application.getAPPLCTN_CD());
logger.info("====**=====>"+application.getId()+" "+application.getAPPLCTN_DS());
logger.info("====**=====>"+application.getId()+" "+application.getAPPLCTN_ID());
logger.info("====**=====>"+application.getId()+" "+application.getDECLG_IDNTFNT_NU());
logger.info("====**=====>"+application.getId()+" "+application.getVersion());
logger.info("====**=====>"+application.getId()+" "+application.getActive());
List<PRM_CONTEXTE> cntxt = cntxtService.findAllOBJECTS();

The issue is fixed by changing the name of the pathVariable, because it was the same as the id and by adding setter for id in my Entity
#RequestMapping(value = { "/edtApp-{i}" }, method = RequestMethod.GET)
public String editApp(#PathVariable int i, ModelMap model) {
//....
}
#RequestMapping(value = { "/edtApp-{i}" }, method = RequestMethod.POST)
public String updateApp(#Valid #ModelAttribute("application") {
//....
}
