    Error rendering template (missing controller)

    Hi there,

    I am trying to render a template but is stuck with this error:

    <!-- Error rendering template with id 1080: 'System.ArgumentNullException: Value cannot be null.Parameter name: controller at System.Web.Mvc.ControllerContext..ctor(RequestContext requestContext, ControllerBase controller)   at Umbraco.Web.Templates.TemplateRenderer.ExecuteTemplateRendering(TextWriter sw, PublishedContentRequest contentRequest)   at Umbraco.Web.Templates.TemplateRenderer.Render(StringWriter writer)   at Umbraco.Web.UmbracoHelper.RenderTemplate(Int32 pageId, Nullable`1 altTemplateId)' -->

    The ID is correct, and I am trying to render it using this:


    The DocType is ContentWidget and I have a ContentWidgetController (have tried with both a SurfaceController and ordinary Controller).

    From dotpeek I have discovered that this property is null:

    Any help would be greatly appreciated :-)

    Thanks in advance!

    I just experienced the same issue with Umbraco 6.1.1.

    Suggested solution is to use @Html.Partial instead:

    I have the same problem, but the above solution does not work for me because I need to render the page in code (not in views/template).

    The ugly solution for me was to download the page

    WebClient client = new WebClient();
    string body = client.DownloadString(library.NiceUrlWithDomain(contentId));

    Same here. I have a module that does some checks and returns the html of some arbitrary node. Currently I am using the application.PreRequestHandlerExecute event to do the checks. Could it be that some MVC plumbing is not in place yet during this event?

    Though ugly I might have to go with @Razvan's solution for the time being...don't like internal request though.
