FacesMessage and general f:message../

Question

I am using the standard validateLength validator in a page and am using <f:message for="username"/> to spit out the horrid standard error message.
But I also need a message to appear at the top of the form if the user just enters wrong credentials. So I did the following in my LoginBean class
public String login()
        if ( username.equals("sam") && password.equals("iam"))
            return "success";
        else
            FacesContext context = FacesContext.getCurrentInstance();
            FacesMessage message = new FacesMessage("Invalid Username and/or Password");
            message.setSeverity(FacesMessage.SEVERITY_ERROR);
            context.addMessage("login", message);
            return "failure";
    }And then in my login.jsp I thought I could place the following line at the top of the form
<h:messages id="login"/> When the credentials are wrong, this works fine. But when the length validator is hit, I also get those error messages at the top of my form. I only want that error message to show up if my login credentials are wrong. Not on the validateLength.
Thanks.

Ok, I figured out that in my LoginBean when I created my FacesMessage I needed to tell it what component to be registered for. So I used the id of my FORM and it worked great.
