Hi all,

As with many people before me it seems, I'm trying to create the contact form surface controller example, but am having a lot of trouble trying to get it to work. I'm getting the following error:

*The model item passed into the dictionary is of type 'Umbraco.Web.Models.PartialViewMacroModel', but this dictionary requires a model item of type 'My.Models.LoginFormViewModel'. *

This is my model (code lifted from the example online):

    namespace My.Models
{
    public class LoginFormViewModel
    {
        [Required]
        public string UserId { get; set; }
    }
}

My controller:

using My.Models;
using System.Web.Mvc;
using Umbraco.Web.Mvc;

namespace My.Controllers
{
    public class LoginFormSurfaceController : SurfaceController
    {
        [ChildActionOnly]
        public ActionResult Index()
        {
            return PartialView("LoginForm", new LoginFormViewModel());
        }

        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult HandleLoginForm(LoginFormViewModel model)
        {
            if (!ModelState.IsValid)
            {
                return CurrentUmbracoPage();
            }

// do some stuff

            TempData["IsSuccessful"] = true;
            return RedirectToCurrentUmbracoPage();
        }
    }
}

And my form:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<LoginFormViewModel>

@using My.Controllers
@using My.Models

@{
    Html.EnableClientValidation(true);
    Html.EnableUnobtrusiveJavaScript(true);
}

@if (Convert.ToBoolean(TempData["IsSuccessful"]))
{
    <h1>YAY!</h1>
    <p>Thanks for sending your message, we will get back to you shortly.</p>
}
else
{
    using (Html.BeginUmbracoForm<LoginFormSurfaceController>("HandleLoginForm"))
    {
        @Html.ValidationSummary(true)
        @Html.AntiForgeryToken()

        @Html.TextBoxFor(model => model.UserId, new { placeholder = "Your ID" })
        @Html.ValidationMessageFor(model => model.UserId)

        <input type="submit" value="Send" />
    }
}

Does anyone have any idea why this isn't working??

I've been at this for hours and have tried almost everything I've found. One thing I found was that this error can be thrown when a null model is being passed, but I don't know how to check for that, why it is happening or what to do to avoid nulls coming through. (bit of an MVC newbie..)
