SpringMVC: How to mark two inputs invalid?

I am using SpringMVC in my webapp to handle forms and their validation.

In my Validator I have code like this:

@Override
public void validate(final Object target, final Errors errors)
{
    final LoginCommand loginCommand = (LoginCommand) target;
    if (checkCredentials(loginCommand.getLogin(), loginCommand.getPassword()) {
        errors.rejectValue("login", "login.error.invalid");
        errors.rejectValue("password", "login.error.invalid");          
    }
    //..

This way I get the properly rendered invalid whenn filling the cssErrorClass attribute. Problem now is that the login.error.invalid message is in the error-message list I am going to display twice.

What is the best way to mark two input fields inva开发者_C百科lid, but only have one message in the error list? I searched the SpringMVC documentation/api all over and did not find a way to reject a field without supplying a message.

I suggest to mark all form as invalid in this case:

if (checkCredentials(loginCommand.getLogin(), loginCommand.getPassword()) {
    errors.rejectValue("login.error.invalid");         
}

And show it on view by

<form:errors />

<%@ taglib uri="spring.tld" prefix="s"%>
<%@ taglib uri="spring-form.tld" prefix="sf"%>

You must limit the sf:errors tag by placing it in a s:bind tag. Here is an example (the path is probabaly not correct for your needs, but is fine for this example) that limits the errors to the login field:

<s:bind path="loginForm.login">
  <sf:errors/>
</s:bind>

Note: I typed this directly into the answer and it's been a while since I used spring mvc.
