Commented Unassigned: Problem with razor values in html-attributes (mvc4 + 5) [157]

I've tested my code with ASP.NET MVC 3 3.0.20105.1 and it works. I want to upgrade to MVC 4 4.0.40804 but this snippet does not work. Even tried with MVC 5.2.2.

Tested with RazorGenerator 2.2.3

This is some simplified example-code from a helper.cshtml:
```
@using System
@* Generator: MvcHelper *@

@functions
{
public HelperResult Message(string msg)
{
return MessageHtml(msg);
}
}

@helper MessageHtml(string msg)
{
<h1>@msg</h1>
<h1 class="@msg">@msg</h1>
}
```

Then I use it in Index.cshtml:
```
@{
var h = new MvcApplication1.Helpers.Helper();
}
@h.Message("hello")
```

The first h1 will work but the other one wont (because of the class-attribute). I need to be able to create functions and reuseable helpers within one cshtml-file.

I get a basic null-reference error ("Object reference not set to an instance of an object").
Suggestions?
Comments: It's at runtime and this is the stack trace: ``` [NullReferenceException: Object reference not set to an instance of an object.] System.Web.Mvc.WebViewPage.get_Context() +15 System.Web.WebPages.WebPageExecutingBase.WritePositionTaggedLiteral(TextWriter writer, String pageVirtualPath, String value, Int32 position) +97 System.Web.WebPages.WebPageExecutingBase.WriteAttributeTo(String pageVirtualPath, TextWriter writer, String name, PositionTagged`1 prefix, PositionTagged`1 suffix, AttributeValue[] values) +409 System.Web.WebPages.WebPageExecutingBase.WriteAttributeTo(TextWriter writer, String name, PositionTagged`1 prefix, PositionTagged`1 suffix, AttributeValue[] values) +42 MvcApplication1.Helpers.<>c__DisplayClass1.<MessageHtml>b__0(TextWriter __razor_helper_writer) in c:\Users\Jesse\Desktop\MvcApplication1 - working Copy 3\helpers\Helper.cshtml:14 System.Web.WebPages.HelperResult.WriteTo(TextWriter writer) +10 System.Web.WebPages.WebPageBase.Write(HelperResult result) +71 ASP._Page_Views_Home_Index_cshtml.Execute() in c:\Users\Jesse\Desktop\MvcApplication1 - working Copy 3\MvcApplication1\Views\Home\Index.cshtml:4 System.Web.WebPages.WebPageBase.ExecutePageHierarchy() +197 System.Web.Mvc.WebViewPage.ExecutePageHierarchy() +97 System.Web.WebPages.StartPage.RunPage() +17 System.Web.WebPages.StartPage.ExecutePageHierarchy() +62 System.Web.WebPages.WebPageBase.ExecutePageHierarchy(WebPageContext pageContext, TextWriter writer, WebPageRenderingBase startPage) +76 System.Web.Mvc.RazorView.RenderView(ViewContext viewContext, TextWriter writer, Object instance) +258 System.Web.Mvc.BuildManagerCompiledView.Render(ViewContext viewContext, TextWriter writer) +115 System.Web.Mvc.ViewResultBase.ExecuteResult(ControllerContext context) +295 System.Web.Mvc.ControllerActionInvoker.InvokeActionResult(ControllerContext controllerContext, ActionResult actionResult) +13 System.Web.Mvc.<>c__DisplayClass1a.<InvokeActionResultWithFilters>b__17() +23 System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter(IResultFilter filter, ResultExecutingContext preContext, Func`1 continuation) +242 System.Web.Mvc.<>c__DisplayClass1c.<InvokeActionResultWithFilters>b__19() +21 System.Web.Mvc.ControllerActionInvoker.InvokeActionResultWithFilters(ControllerContext controllerContext, IList`1 filters, ActionResult actionResult) +177 System.Web.Mvc.Async.<>c__DisplayClass2a.<BeginInvokeAction>b__20() +89 System.Web.Mvc.Async.<>c__DisplayClass25.<BeginInvokeAction>b__22(IAsyncResult asyncResult) +102 System.Web.Mvc.Async.WrappedAsyncResult`1.End() +57 System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeAction(IAsyncResult asyncResult) +43 System.Web.Mvc.<>c__DisplayClass1d.<BeginExecuteCore>b__18(IAsyncResult asyncResult) +14 System.Web.Mvc.Async.<>c__DisplayClass4.<MakeVoidDelegate>b__3(IAsyncResult ar) +23 System.Web.Mvc.Async.WrappedAsyncResult`1.End() +62 System.Web.Mvc.Controller.EndExecuteCore(IAsyncResult asyncResult) +57 System.Web.Mvc.Async.<>c__DisplayClass4.<MakeVoidDelegate>b__3(IAsyncResult ar) +23 System.Web.Mvc.Async.WrappedAsyncResult`1.End() +62 System.Web.Mvc.Controller.EndExecute(IAsyncResult asyncResult) +47 System.Web.Mvc.Controller.System.Web.Mvc.Async.IAsyncController.EndExecute(IAsyncResult asyncResult) +10 System.Web.Mvc.<>c__DisplayClass8.<BeginProcessRequest>b__3(IAsyncResult asyncResult) +25 System.Web.Mvc.Async.<>c__DisplayClass4.<MakeVoidDelegate>b__3(IAsyncResult ar) +23 System.Web.Mvc.Async.WrappedAsyncResult`1.End() +62 System.Web.Mvc.MvcHandler.EndProcessRequest(IAsyncResult asyncResult) +47 System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.EndProcessRequest(IAsyncResult result) +9 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +9657896 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +155 ```
