I'm trying to post form data from a view that is hijacked. The issue that I'm having is that I can't seem to get the model to post back.

What I would think I should do is something like this...

    [HttpPost]
    [ValidateUmbracoFormRouteString]
    [ValidateAntiForgeryToken]
    public ActionResult Index(LocationViewModel model)
    {
        return View(model);
    }

However that return an error, Cannot bind source content type Umbraco.Cms.Web.Common.PublishedModels.Location to model type Portal_Core.ViewModel.LocationViewModel

I've tried following the documentation https://our.umbraco.com/Documentation/Reference/Routing/custom-controllers but I can't seem to find any examples of posting the model back to the controller.

In Umbraco I have a page called 'Location'

I have 'LocationController : RenderController' to handle the hijack and [HttpGet] to serve the ViewModel.

The ViewModel is called 'LocationViewModel'. The page uses as master page so the view model implements ' : PublishedContentWrapped'

    public class LocationViewModel : PublishedContentWrapped
{

    public LocationViewModel(IPublishedContent content, IPublishedValueFallback publishedValueFallback) : base(content, publishedValueFallback)
    {

    } ...

In the location view I'm using @inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Portal_Core.ViewModel.LocationViewModel>

In the form I'm using @using (Html.BeginUmbracoForm<Portal_Core.Controllers.LocationFormController>("Index"))

LocationFormController is a : SurfaceController

In the LocationFormController post I can see the data by using

public IActionResult FormPost(IFormCollection collection)

all of the form data is in the collection so I know it is posting but then I've lost the model.

I can use

public IActionResult Index(ContentModel<IPublishedContent> model)

to see the Location (the non hijacked model) but I can't seem to get the LocationViewModel (Hijacked Model).

Unfortunately all of the example that I've found show a parameterless Post method and don't show how to get the hijacked model back.

Does anyone have any advice or examples on getting that posted model?

Thanks!
