Accessing Session in the ServiceStack Razor View
I am trying to access the session inside a ServiceStack Razor View (Partial). In this case I am just trying to render our the menu which exists in the session.
@(new HtmlString(this.SessionAs<CustomUserSession>().MenuHtmlString))
I get this error:
Response Status
Error Code NullReferenceException Message Object reference not set to an instance of an object. Stack Trace [BOPBasicInfo1VM: 1/31/2014 9:46:45 PM]: [REQUEST: {QuoteNumber:1,AgencyId:0,Errors:[],IsValid:False}] System.NullReferenceException: Object reference not set to an instance of an object. at ASP._BOPBasicInfo1VM.Execute() at ServiceStack.Razor.ViewPage 1.WriteTo(StreamWriter writer) at ServiceStack.Razor.Managers.RazorPageResolver.ExecuteRazorPageWithLayout(IRequest httpReq, IResponse httpRes, Object model, IRazorView page, Func 1 layout) at ServiceStack.Razor.Managers.RazorPageResolver.ResolveAndExecuteRazorPage(IRequest httpReq, IResponse httpRes, Object model, RazorPage razorPage) at ServiceStack.Razor.Managers.RazorPageResolver.ProcessRequest(IRequest httpReq, IResponse httpRes, Object dto) at ServiceStack.Formats.HtmlFormat.<>c_DisplayClass2.b__0(IViewEngine x) at System.Linq.Enumerable.Any[TSource](IEnumerable 1 source, Func 2 predicate) at ServiceStack.Formats.HtmlFormat.SerializeToStream(IRequest request, Object response, IResponse httpRes)
Am I trying to access the session correctly? Any ideas as to why this is failing?
As far as I know there is no break point/debug support in the SS Razor Views, has that changed with the latest version v4.0.8.0+?
The issue turned out to be with the
@(new HtmlString())
instead of the
this.SessionAs<CustomUserSession>().MenuHtmlString
The way that I figured that out was by creating a static method on a class and passing "this" into it so that I could debug.
public static HtmlString GetMenu(ServiceStack.Razor.ViewPage page)
{
return new HtmlString(page.SessionAs<FMIC.DTOs.Entities.CustomUserSession>().MenuHtmlString);
}
And calling it like this from the view.
@(ViewPageExtensions.GetMenu(this))
I will also add a comment from Demis (mythz) from the ServiceStack Forums
To help with debugging I would call your own method from Razor views so you can put a breakpoint and inspect the values passed in.
You should also hopefully be able to debug v4.09 source code using the source symbols published with NuGet, some instructions: https://github.com/ServiceStack/ServiceStack/wiki/Debugging#wiki-debugging-source-symbols-in-nuget-packages
