Hello,

Recently I used Ditto in a SurfaceController called through an Ajax call, and I was surprised to see the conversion of my IEnumberable<IPublishedContent> return null when converting with the Ditto .As<> extension method.

It took me quite a while to figure out that the extension method required a value for the culture parameter. When hijacking a route with a controller inheriting from RenderMvcController this was not necessary, but apparently this culture context is missing when calling a controller through an Ajax call. I'm showing the code because I thought this was not obvious at all, it may save somebody some time.

public class CarController : SurfaceController
{
    public ActionResult Get()
    {
       CultureInfo cultureInfo = new CultureInfo("nl-NL");  

       var segmentId = Convert.ToInt32(Request["segmentid"]);
        var segmentRoot = Umbraco.TypedContent(segmentId); 

     IEnumerable<IPublishedContent> cars = segmentRoot.Descendants(DocumentTypes.CarPage).ToList();

          // cars.As<CarPage>() returns null if the culture parameter is lacking.
       IEnumerable<CarPage> typedCarList = cars.As<CarPage>(culture:cultureInfo).ToList();

       return View("~/Views/Partials/CarList.cshtml", typedCarList);
    }
}
