FilterAttribute Order not working

Question

I have 2 attributes that I use within the controllers of my MVC application. AttributeA extends System.Web.Mvc.AuthorizeAttribute and AttributeB extends System.Web.Mvc.ActionFilterAttribute. I want AttributeB to always be run first.

I have tried all possible combinations of Order based on this article, but AttributeA is always run before AttributeB. Can anyone help?

If you look at the System.Web.Mvc.ControllerActionInvoker.InvokeAction method with reflector you will see that all filters implementing IAuthorizationFilter are invoked before attributes deriving from ActionFilterAttribute and that's because authorization is made before invoking the action.
