ASP.NET MVC Appends ' ?RouteValueDictionary ' to my routes

Question

Hi,

I'm doing some changes on my routes, and suddenly the following is appearing in my url's as a querystring:

?RouteValueDictionary=System.Web.Routing.RouteValueDictionary

So, my url's now look like

http://localhost:20367/Search/AdvancedSearchResults?RouteValueDictionary=System.Web.Routing.RouteValueDictionary

How do I make it disappear?

I know the routing puts it in there, because it cannot find route values for the viewmodel that's passed along, but I can't seem to fix it...

I suspect your call to Html.ActionLink is picking the wrong overload. You might need to add an extra parameter at the end to force .NET to pick the right overload:

Html.ActionLink("click here, "SomeAction", "SomeController", routeValues, null)
