Hello, I'm trying to create contact form on a bazaar store. I've done very similar without issue on other Umbraco sites. I get a 'No parameterless constructor' error.

I've been unable to identify what's causing this, despite stepping through with visual studio.

Here's the format:

New document type: 'ContactForm'

Hijacked the route:

  public class ContactFormController : RenderControllerBase
{

    public override ActionResult Index(RenderModel model)
    {
        var viewModel = new ContactUsModel(model.Content); { };
        viewModel.CurrentCustomer = this.CurrentCustomer;
        return View(viewModel.ThemeViewPath("ContactForm"), viewModel);
    }
}

Model (inherits from MasterModel for the ICustomerBase)

   public class ContactUsModel : MasterModel
{
    public ContactUsModel(IPublishedContent content) : base(content)
    {
    }

    [Required]
    public string Name { get; set; }
    [Required]
    public string TelephoneNumber { get; set; }
    [EmailAddress]
    public string Email { get; set; }
    [Required]
    public string Message { get; set; }

    public int ThankYouPage { get; set; }
}

ContactForm view:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<Models.Contact.ContactUsModel>
@{
Layout = "Master.cshtml";
}

@Html.ThemedPartial(Model.Theme, "_ContactUs", new ContactUsModel(Model){ThankYouPage = Model.GetPropertyValue<int>("thankyoupage")})

Partial view:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<Models.Contact.ContactUsModel>

@using (var form = Html.BeginUmbracoForm<ManxIndependentTradingGroup.Controllers.Contact.ContactFormSurfaceController>("HandleFormSubmit"))
{
@Html.AntiForgeryToken()

<div class="row">
    <div class="col-xs-12 col-md-6 col-md-offset-3">
        <div class="">
            <label class="form-label" for="">Contact Name @Html.ValidationMessageFor(m => m.Name)</label>
            <div class="input-group">
                @Html.TextBoxFor(m => m.Name, new { @class = "form-field", placeholder = "Enter Name", required = "required" })
            </div>
        </div>
        <div class="">
            <label class="form-label" for="">Telephone Number @Html.ValidationMessageFor(m => m.TelephoneNumber)</label>
            <div class="input-group">
                @Html.TextBoxFor(m => m.TelephoneNumber, new { @class = "form-field", placeholder = "Enter Telephone Number", required = "required" })
            </div>
        </div>
        <div class="form-group">
            <label class="form-label" for="">Email Address @Html.ValidationMessageFor(m => m.Email)</label>
            <div class="input-group">
                @Html.TextBoxFor(m => m.Email, new { @class = "form-field", placeholder = "Enter Email", required = "required" })
            </div>
        </div>
        <div class="form-group">
            <label class="form-label" for="">Message @Html.ValidationMessageFor(m => m.Message)</label>
            <div class="input-group">
                @Html.TextAreaFor(m => m.Message, new { @class = "form-field", rows = 8, required = "required" })
            </div>
        </div>

        @Html.HiddenFor(x => x.ThankYouPage)

        <input type="submit" name="submit" id="submit" value="Submit">
    </div>
</div>
}

At this point the page loads as expected, with the contact form. On submit of the form I receive the 'No parameterless constructor'

Surface controller - my breakpoints aren't being hit on this class..

 public class ContactFormSurfaceController : SurfaceController
{
    [ValidateAntiForgeryToken()]
    public ActionResult HandleFormSubmit(ContactUsModel model)
    {
        if (!ModelState.IsValid)
        {
            return CurrentUmbracoPage();
        }

        //send email

        return RedirectToUmbracoPage(model.ThankYouPage);

    }
}

Would appreciate some assistance here guys.

cheers
