Required fields name

[sandstorm]

Hi.
Consider these classes

public class Registration {
    private Subject user = new Subject();
    private String passwordConfirmation;
}


public class Subject{
    private String name;
    private String password;
}

public class RegistrationController extends SimpleFormController {
    private static final String[] REQUIRED_FIELDS = new String[]{
	"user.name",
	"user.password",
	"passwordConfirmation"
    };
    
    @Override
    public void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {
	binder.setRequiredFields(REQUIRED_FIELDS);
    }
}

Are the REQUIRED_FIELDS correctly specified ?
How should they be specified anyway if they aren't?

Thanks !


P.S. the "user" thing is like in "e.pushNestedPath("user");"

if (e.getFieldErrorCount("passwordConfirmation") == 0 && !reg.getUser().getPassword().equals(reg.getPasswordConfirmation())) {
	    e.rejectValue("passwordConfirmation", "passwordConfirmationMismatch");
	}

When execution goes to this, then getPassword returns null, and NullPointerException gets raised.

Somewhere something is wrong... Can you help me find what it is ?
