StructureMap controller factory and null controller instance in MVC

Question

I\'m still trying to figure things out with StructureMap and one of the issues i\'m running into is my Controller Factory class blowing up when a null controller type is passed

Answer 1

I ran into the same problem with a controller factory built around ninject.

It seems MVC will pass you null for controllertype when it can't resolve a route from the routing table or when a route specifies a none existing controller. I did two things to solve this. You might want to check your route table and add a catchall route that shows a 404 error page like described here .Net MVC Routing Catchall not working

You could also check with the routing debugger what goes wrong. http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx
