Question

My controller actions:

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Login()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Login(string UserName, string Password, bool RememberMe)
    {
        var userNameValidationResults = _validatorProvider.Validate<IMailAddressValidator>(UserName);
        foreach (var result in userNameValidationResults.Where(r => !r.Passed)) {
            ModelState.AddModelError("UserName", result.ErrorMessage);
        }

        var passwordValidationResults = _validatorProvider.Validate<IStringLengthValidator>(Password);
        foreach (var result in passwordValidationResults.Where(r => !r.Passed)) {
            ModelState.AddModelError("Password", "Please enter a password.");
        }

        if (!ModelState.IsValid)
            return View();

        bool validUser = _userMembershipService.ValidateUser(UserName, Password);

        if (!validUser) {
            ModelState.AddModelError("_FORM", "Invalid e-mail address and/or password.");
            return View();
        }

        _userAuthenicationService.Login(UserName, RememberMe);

        return RedirectToAction("Index", "Home");
    }

My view:

<h2>Login</h2>
<%= Html.ValidationSummary() %>
<% using (Html.BeginForm()) { %>
    <%= Html.TextBox("UserName") %>
    <%= Html.Password("Password") %>
    <%= Html.CheckBox("RememberMe") %>
    <input type="submit" value="Login" />
<% } %>

If I submit the form again after a validation error, I get another error (the same exact error) in the ValidationSummary. Why is that happening? Thanks.

Edit What I mean is that I have n-number of errors where n is the number of submissions.

Edit 2
What I now am having a problem it looks like it is remaining persistant – even the form field values won’t change. I updated my code above. Also, I am using Castle Windsor for an IoC container, but I don’t think that would be the source of my problem. But for the case it could be, here is the source I am using to register my controllers.

        container.Register(
            AllTypes
                .FromAssemblyNamed("Aplication")
                .BasedOn<IController>()
                .Where(t => t.Name.EndsWith("Controller"))
                .Configure(c => c.LifeStyle.Is(LifestyleType.Transient))
                .WithService
                .FirstInterface()
            );

Answer 1

Actually, it was my Castle Windsor configuration.

 container.Register(
        AllTypes
            .FromAssemblyNamed("Aplication")
            .BasedOn<IController>()
            .Configure(c => c.LifeStyle.Is(LifestyleType.Transient))
            .WithService
            .FirstInterface()
        );

Its weird I can’t do the based on and the where clause at the same time.
