I have a problem where the code in my custom controller does not get executed. I think i have followed the guide correctly found here: https://our.umbraco.com/documentation/reference/routing/custom-controllers But the result does not reflect it as it does not work.

Controller:

public class FrontPageController : RenderMvcController
{
    public override ActionResult Index(ContentModel model)
    {
        //InitializeBaseModel(model);
        //var blogService = new BlogService();
        var frontPageModel = new FrontPageModel(model.Content);
        frontPageModel.Headline = frontPageModel.Value<string>("headline");


        return CurrentTemplate(model);
    }


}

The alias for the document type is FrontPage

Model:

public class FrontPageModel : BaseModel
{

    public string Headline { get; set; }


    public FrontPageModel(IPublishedContent content) : base(content)
    {
    }
}

Template named FrontPageTemplate starts with the following and has a mastertemplate that does not have any model, but just a @RenderBody:

@inherits UmbracoViewPage

I get this error:

Any help would be very much appreciated as i have been struggling for several long hours without any improvement and google has not been my friend!
