Hi,

Thanks in advance for your help.

I am using Umbraco 7.11.1, I created custom controller in visual studio, Which inherits SurfaceController. And inherits UmbracoViewPage in view.

Here is the sample code,

Model:

 public class CompanyModel {...}

View:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
    @inherits UmbracoViewPage<Business.CompanyModel>

@using (Html.BeginForm("Company", "CoverSurface", FormMethod.Post, new { @role = "form",  @novalidate = "novalidate" }))  ...

Controller:

 public class CoverSurfaceController : SurfaceController    {
public ActionResult Company()
        {
           var model = new CompanyModel()
                {
                    //call to generate model
                };

                return View(model);
        }
}

When i run in debug, Routing happens fine and I can see the control hitting right action and view. And the end of view debug, its throwing exception as follows :

Cannot bind source type Business.CompanyModel to model type Umbraco.Web.Models.RenderModel.
