Hi all, I'm a beginner just learning how to use Episerver and I was doing the free online training course and after doing one particular exercise I keep getting this error when I go to the start page of my episerver site:

The model item passed into the dictionary is of type 'Castle.Proxies.StartPageProxy', but this dictionary requires a model item of type 'AlloyTraining.Models.ViewModels.PageViewModel`1[AlloyTraining.Models.Pages.StartPage]'.

The edit page works, but the live view does not.   Anyone know how to fix this?

Relevant files:

             * you can pass the page type for simpler templates */

            return View(currentPage);

Not really sure what file is messing things up or where to look.


Here is the full error if that helps:

Your view expects the model to be `PageViewModel<AlloyTraining.Models.Pages.StartPage>`  but in your controller, you are passing `AlloyTraining.Models.Pages.StartPage`.

Could you try changing your Controller to this?

public ActionResult Index(StartPage currentPage)
{
   var model = PageViewModel.Create(currentPage);
   return View(model);
}
