Problem with checkbox and model

[gargantua]

Hi,

Please, accept my apologies because english is not my mother language.

I have a web application with Spring 3.2.1 (core, web, mvc)
All was working fine until i tried to create a form with a checkbox mapped on a Boolean value.

If i check the box, no problem.
But if i don't, then i got the following error :

org.springframework.beans.NotReadablePropertyException: Invalid property 'charteAccepted' of bean class [com.teamIT.common.dto.utilisateur.UserDTO]: Bean property 'charteAccepted' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
	at org.springframework.beans.BeanWrapperImpl.getPropertyValue(BeanWrapperImpl.java:707)
	at org.springframework.beans.BeanWrapperImpl.getPropertyValue(BeanWrapperImpl.java:699)
	at org.springframework.validation.AbstractPropertyBindingResult.getActualFieldValue(AbstractPropertyBindingResult.java:99)
	at org.springframework.validation.AbstractBindingResult.rejectValue(AbstractBindingResult.java:105)
	at org.springframework.validation.AbstractErrors.rejectValue(AbstractErrors.java:118)
	at com.teamIT.web.validator.SignupValidator.validate(SignupValidator.java:54)
	at com.teamIT.web.controller.authentification.SignupController.signup(SignupController.java:61)
	[...]

I think its because the field is not submitted (when uncheck) but since i use spring form taglib, i know that there is a hidden field that should reflect the value, so Spring should be able to get a value.

So, after many search, i don't understand what is wrong in my code.
Hope you can help me.

There is my code (relevant extract):

jsp file :

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<form:form id="signupForm" action="/signup.do" method="post" modelAttribute="user">
   [...]
   <form:checkbox id="chart" path="chartAccepted" />
   [...]

Note that for some reasons, the form is submit by Javascript doing something like

document.forms["signupForm"].submit();

My Controller :

@Autowired
private SignupValidator signupValidator;

@Autowired
private IUserService userService;

@Autowired
private PasswordEncoder passwordEncoder;

@InitBinder
public void binder(Locale locale, WebDataBinder binder) {
	binder.registerCustomEditor(Date.class, new DateEditor(locale));
}

@RequestMapping(method = RequestMethod.GET)
public String signup(@ModelAttribute("user") UserDTO user) {
	return "public/signup";
}

@RequestMapping(method = RequestMethod.POST)
public String signup(@Valid @ModelAttribute("user") UserDTO user,
			BindingResult result, RedirectAttributes redirectAttributes) {

        //Additional validator (using both JSR-303 and spring Validator)
	signupValidator.validate(user, result);

	if (result.hasErrors()) {
		return "public/signup";
	}

	String encodedPassword = passwordEncoder.encode(user.getPassword());
	user.setPassword(encodedPassword);
	user.setActive(true);

	userService.saveNewUser(user);

	redirectAttributes.addFlashAttribute("message",
			"You have successfully signed up and logged in.");

	return "redirect:/";
}

my model (DTO) :

public class UserDTO extends AbstractDto {

@NotNull(message = "{champ.obligatoire}")
private Boolean chartAccepted;

/**
 * @return the chartAccepted
 */
public Boolean getChartAccepted() {
	return chartAccepted;
}

/**
 * @param chartAccepted
 *            the chartAccepted to set
 */
public void setChartAccepted(Boolean chartAccepted) {
	this.chartAccepted = chartAccepted;
}

}

And my validate methde from my validator class :

@Override
	public void validate(Object target, Errors errors) {

		if (target instanceof UserDTO) {
			UserDTO userDTO = (UserDTO) target;

			if (!userDTO.getChartAccepted()) {
				errors.rejectValue("charteAccepted",
						"error.signupForm.chartNotAccept");
			}

			String email = userDTO.getEmail();
			if (userService.findUserByEmail(email) != null) {
				errors.rejectValue("email",
						"error.signupForm.email.alreadyExist");
			}

		}

	}

So, what is wrong ?

Thanks

Found the problem, got un extra "e" on my string :

if (!userDTO.getChartAccepted()) {
				errors.rejectValue("charteAccepted",
						"error.signupForm.chartNotAccept");
			}

Problem solved.
