copied!<p><code>VirtualPathProviderViewEngine.GetPathFromGeneralName</code> must be changed to allow an additional parameter from the route. Its not public, that's why you have to copy <code>GetPath</code>, <code>GetPathFromGeneralName</code>, <code>IsSpecificPath</code> ...over to your own <code>ViewEngine</code> implementation.</p> <p>You are right: this looks like a complete rewrite.
