In the following discussion its the case that multiple calls to C1PageRoute.GetRouteData gives an error https://compositec1.codeplex.com/discussions/352703.
This is due to the method setting a flag that it has been called, and next time the following line will fail
Verify.IsFalse(context.Items.Contains(HttpContextItem_C1PageUrl), "C1PageRoute was executed twice during the same request. If could be f.e. because there's an MVC player that have a route that matches a C1 page url.");
Looks to me that this line tries to fix a problem with the MVC player, but either way this is wrong. You should be able to call GetRouteData as many times you want without it failing.
