Item has already been added. Key in dictionary: 'Owin.AuthorizationController' Key being added: 'Owin.AuthorizationController'

The above error seems to occur if you have a controller action that calls child actions when creating the layout. If both actions use the same policy in the same controller the ResourceAuthorizeAttribute is adding the same key to the HttpContext.

Example Code to trigger this scenario: ` [ResourceAuthorize(Policy = PolicyType.HasPigsAndGoats)] public class TagsController : BaseController {

    public ActionResult Index() {
        var model = new FakeModel();
        return View(model);
    }

            [ChildActionOnly]
            public ActionResult Goats(){
                  var model = new FakeGoat();
                  return PartialView(model);
            }

} `

Index.cshtml would have something like this...

Pigs are here, goats are loading through the child action

@Html.Action("Goats")

I believe this happens because of line 33 in ResourceAuthorizeAttribute...

filterContext.HttpContext.Items.Add(s_controllerKey, filterContext.Controller);

Could the s_controllerKey variable be based on the controller and action names? Maybe that's an over simplification? Or perhaps it would be enough to just check and see if the key is already there?

Good find. I'll apply a simple fix to remediate the issue.

The fix is available in version 1.1.1.1
