问题 The call was working fine until I installed ASP.NET MVC 1.0 RTM.

Using an abstract controller base, I can define a default "sidebar strategy", which can then be refined by overriding the method in a concrete controller, when needed. The only "problem" I have with this approach, is that the RenderAction is built in a way where it always
