title: Trouble with MVCContrib InputForm<T> and SparkViewEngine
body: <p>I am trying to use MVCContrib InputBuilders but I am having trouble.  I am also using S#arp architecture and spark.  My spark view looks like this:</p>
  
  <p>new.spark:</p>
  
  <pre><code>&lt;viewdata model="NewUserViewModel" /&gt;
  ${Html.InputForm&lt;NewUserViewModel&gt;()}
  </code></pre>
  
  <p>My global.asax.cs contains:</p>
  
  <pre><code>  protected void Application_Start() {
      XmlConfigurator.Configure();
      var controller = InitializeServiceLocator();
      ModelBinders.Binders.DefaultBinder = new SharpModelBinder();            
      ViewEngines.Engines.Clear();
      InputBuilder.BootStrap();
      ViewEngines.Engines.Add(controller.Resolve&lt;IViewEngine&gt;());
      RouteRegistrar.RegisterRoutesTo(RouteTable.Routes);
    }
  </code></pre>
