Spring mvc form submission bindingresult throws error - spring

Question

So my bindingresult throws an error but I'm not able to see it for some reason and I'm not able to figure out what the problem is. I'm guessing the problem lies with the variable targetDate where there is a problem the type. I've pasted my controller and JSP code below. Any help is appreciated!
#Controller
public class ToDoController {
#Autowired
private ToDoService service;
// All date parameters displayed as mm/DD/yyyy
#InitBinder
protected void initBinder(WebDataBinder binder) {
SimpleDateFormat dateFormat = new SimpleDateFormat("mm/DD/yyyy");
binder.registerCustomEditor(Date.class, new CustomDateEditor(
dateFormat, false));
}
#RequestMapping(value = "/list-todo", method= RequestMethod.GET)
// HttpSession allows access to the session
public String showToDo(ModelMap model, HttpSession httpSession) {
String user = (String) httpSession.getAttribute("name");
model.addAttribute("todos", service.retrieveTodos(user));
return "list-todos";
}
// redirect to update form
#RequestMapping(value = "/update-todo", method= RequestMethod.GET)
public String getUpdateForm(ModelMap model, #RequestParam int id) {
System.out.println("ID " + id);
// To work with command bean
model.addAttribute("id", id);
model.addAttribute("todo", service.retrieveTodo(id-1));
return "updateToDo";
}
// What does Valid do?
#RequestMapping(value = "/update-todo", method= RequestMethod.POST)
public String submitUpdate(ModelMap model, #Valid ToDo todo, BindingResult result) {
if (result.hasErrors()) {
System.out.println("ERROR" + result.getAllErrors());
// Redirect and pass on the id value
return "redirect:/update-todo?id=" + todo.getId();
}
System.out.println("Update todo" + todo);
service.updateToDo(todo);
model.clear();
return "redirect:/list-todo";
}
// Will be executed first
#RequestMapping(value = "/add-todo", method= RequestMethod.GET)
public String showAddForm(ModelMap model) {
model.addAttribute("todo", new ToDo());
return "addToDo";
}
/*
* Will be executed after form is submitted
* #Valid ToDo - command bean from addToDo.jsp.
* #Valid to validate the information
* #BindingResult showcases the result of the validation
*/
#RequestMapping(value = "/add-todo", method= RequestMethod.POST)
public String submitAddForm(ModelMap model , #Valid ToDo todo, HttpSession httpSession, BindingResult result) {
System.out.println("running" + result);
// If there is validation error , return to addToDos page for user to fix the error
if (result.hasErrors()) {
return "redirect:/showAddForm?id=?" + todo.getId();
}
String user = (String) httpSession.getAttribute("name");
service.addTodo(user, todo.getDescription(), todo.getTargetDate(), false);
// Clears the url e.g. name?=jyj123
model.clear();
// return to the url which executes the showToDO
return "redirect:/list-todo";
}
// delete to do entry
#RequestMapping(value = "/delete-todo", method= RequestMethod.GET)
public String deleteToDo(ModelMap model, #RequestParam int id) {
service.deleteTodo(id);
model.clear();
return "redirect:/list-todo"; }
}
My JSP

In your jsp you submit the form to "todo", not "update-todo". It would be nice to see your ToDo bean. Also: result.getAllErrors().
