Form:Options working pretty well, but if I submit wrong data in Form, form:options in newContact.jsp shows the first element of departmentList as selected.
ContactController:
#RequestMapping(value="/saveContact", method=RequestMethod.GET)

ModelAndView mav = new ModelAndView("newContact");
// Contact contact = new Contact();

User user = (User)SecurityContextHolder.getContext().getAuthentication().getPrincipal();
String name = user.getUsername();
mav.addObject("username", name);
mav.addObject("newContact", new Contact());
// mav.addObject("department", department);
mav.addObject("departmentList", departmentService.listDepartment());
//mav.getModelMap().put("newContact", contact);
return mav;
}
#RequestMapping(value="/saveContact", method=RequestMethod.POST)
public String create(#ModelAttribute("newContact")Contact contact, BindingResult result, SessionStatus status,Map<String, Object> map)
{
User user = (User)SecurityContextHolder.getContext().getAuthentication().getPrincipal();
String name = user.getUsername();
map.put("departmentList", departmentService.listDepartment());
map.put("username", name);
contactFormvalidator.validate(contact, result);

Instead of returning String in your submit method return ModelAndView ...
#RequestMapping(value="/saveContact", method=RequestMethod.POST)
public ModelAndView create(#ModelAttribute("newContact")Contact contact, BindingResult result, SessionStatus status,ModelMap map)
{
User user = (User)SecurityContextHolder.getContext().getAuthentication().getPrincipal();

map.addAttribute("departmentList", departmentService.listDepartment());
map.addAttribute("username", name);
contactFormvalidator.validate(contact, result);
if (result.hasErrors())
{
return new ModelAndView("newContact",map);
}
contactService.addContact(contact);
status.setComplete();
//return new ModelAndView("redirect:/showContacts.do");
return new ModelAndView("newContactSuccess");

I'm having problems with validating in Spring. I'm getting the following error after opening the form:
java.lang.IllegalStateException: Invalid target for Validator [com.example.validator.UserValidator#6ac0a8f4]: com.example.web.forms.UserDTO#4d3b2379
My Validator for the time being, wanted to check if anything works first:
#Component
public class UserValidator implements Validator {
#Autowired
ServiceUser serviceUser;
#Override
public boolean supports(Class<?> clazz) {
return User.class.equals(clazz);
}
#Override
public void validate(Object target, Errors errors) {
User user = (User) target;
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "name", "NotEmpty.userForm.name");
}
}
Controller:
#Controller
public class UserController {
#Autowired
UserValidator userValidator;
#InitBinder
public void initBinder(WebDataBinder binder) {
CustomDateEditor editor = new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true, 10);
binder.registerCustomEditor(Date.class, editor);
binder.setValidator(userValidator);
// binder.addValidators(userValidator);
}
final static Logger logger = Logger.getLogger(UserController.class);
#Autowired
protected ServiceUserImpl service;
#RequestMapping("/lista")
public String showIndex(Model model) {
User contest = new User();
model.addAttribute("element", contest);
model.addAttribute("collection", service.findAll());
return "lista";
}
#RequestMapping("/dodaj")
public String showFormPublication(HttpServletRequest request, #ModelAttribute("userDto") #Valid UserDTO userDTO, BindingResult result) {
if (request.getMethod().equalsIgnoreCase("post") && !result.hasErrors()) {
if (result.hasErrors()) {
return "forms/contest";
} else {
User user = new User();
user.setId(userDTO.getId());
user.setName(userDTO.getName());
user.setSurname(userDTO.getSurname());
user.setDateOfBirth(userDTO.getDateOfBirth());
user.setIndexNumber(userDTO.getIndexNumber());
user.setEmail(userDTO.getEmail());
service.save(user);
return "redirect:/lista";
}
}
return "dodaj";
}
}
Form in .jsp:

I tried adding ("userDto") next to #InitBinder, it didn't help unfortunately. Haven't found much more in terms of applicable solutions. If there's anything else I should post here let me know. I can also provide a link to repository should anyone be eager enough to try to run it.
I think you need to change the supports method in UserValidator to UserDTO class:
public boolean supports(Class<?> clazz) {
return UserDTO.class.equals(clazz);
}

I am trying so many time but unable to fixed the issue, And browse also but did't get any proper help, so please help to do items
I NEED HELP PLEASE SOME BODY HELP ME...!
Thank you in advance
I think the problem is in your jsp file.
You need to set the index of each list element.
<c:forEach items="${List2}" var="as" varStatus="vs">
<tr class="rule">
<td><input type="hidden" name="ruleList[${vs.index}].id" value="${as.rule.id}" /> ${as.rule.id}</td>
<td><input type="hidden" name="ruleList[${vs.index}].ruleName" value="${as.rule.ruleName}" /> ${as.rule.ruleName}</td>
<td> <input id="one" class="datepicker" type="text" name="ruleList[${vs.index}].startDate" size="11" height="0.10"></td>
<td> <input id="two" class="datepicker" type="text" name="ruleList[${vs.index}].endDate" size="11" height="0.10"></td>
<td>
<table border="1">
<c:forEach items="${as.ruleAssignmentParameter}" var="asss" varStatus="assignments">
<tr>
<td><input type="hidden" name="ruleList[${vs.index}].ruleAssignmentParameter[${assignments.index}].parameterName" value="${asss.parameterName}" > ${asss.parameterName}</td>
<td><input type="hidden" name="ruleList[${vs.index}].ruleAssignmentParameter[${assignments.index}].overwriteValue" value="${asss.overwriteValue}" /> ${asss.overwriteValue}</td>
</tr>
</c:forEach>
</table>
</td>
</tr>
</c:forEach>
Also in your controller (POST method) you are trying to get the object identified by "SpringWeb" but should be "ruleListContainer", same name you have in your form tag
The problem was you had a list into RuleAssUI and you was not accesing correctly, you need 2 loops and indexes, one for each list.
Here is the key:
ruleList[${vs.index}].ruleAssignmentParameter[${assignments.index}].parameterName
I have a restaurant edit page located "/restaurant/edit/{id}". From that page I can (among other things) add tables to the restaurant by pressing an "Add tables" button. That button takes me to another page located "/restaurant/edit/{id}/table". The question is, after I have added the table - how do I get back to the previous page by pressing a button? Right now my contoller is returning "editRestaurant.jsp" which is the right value, but I don't know how to pass that same restaurant id as well. I hope you understand what I mean.

#RequestMapping(value = "restaurant/{id}/table", method = RequestMethod.POST)

After successful POST you should do a redirect.
Something like this:
return "redirect:/restaurant/edit/" + restaurant.getId();
or
return new RedirectView("/restaurant/edit/" + restaurant.getId(), false);
There is a different method you can use to return the model that will include the parameter. I believe this may solve your problem.
#RequestMapping(value = "restaurant/edit/{id}", method = RequestMethod.GET)
public String editRestaurant(#PathVariable Long id, Model model) {
Restaurant restaurant = restaurantService.getRestaurant(id);
return new ModelAndView("editRestaurant", "restaurant", restaurant);
}
I want to take get a url parameter again after I've done another method. I tried adding the line new ModelAndView (updatealbum.htm?albumId=${album.albumId}"); but failed.
My path when I click the edit link is:
http://localhost:8089/MusicStore/admin/updatealbum.htm?albumId=13
My path after press submit button:
http://localhost:8089/MusicStore/admin/submitupdatealbum.htm?albumId=13
But when I click submit again:
http://localhost:8089/MusicStore/admin/submitupdatealbum.htm?albumId=

Use it
#RequestMapping(value = "*/submitupdatealbum.htm", method = RequestMethod.POST)
public ModelAndView submitUpdateAlbum(
#Valid #ModelAttribute("album") Album album, BindingResult result,
#RequestParam(value = "albumId") int albumId, ModelMap model) {
System.out.println("ssssssssssssssssss:" + result);

System.out.println("result:" + result);
System.out.println("asdasdasd");
ModelAndView model1 = new ModelAndView(

return model1;
}
