The ComponentController can´t return the ActionResult - it´s still "void". Will this issue be solve in the next release or is the ComponentController "obsolent"?

What is the ComponentController? I'm assuming that's something in MvcContrib. If so, you should post that question to their forums.

No - the ComponentController is from your team:

I use this special controller to display dynamic data on an masterpage:

Wow, indeed you're right. I think this may be an experimental class someone should not have left in there. I'll look into it.

Indeed, ComponentController is used by some of the rendering helpers to render sub-components. We didn't update that class yet in part since we're considering some brand new designs for implementing sub-controllers and sub-components. If you need that class you might want to consider just using Preview 2 until we've hashed out all the details.

 Ah - thanks for the info.

It still works (for now) - I just wonder why this controller don´t return an ActionResult.

I hope you guys decide to keep and enhance this feature.

Perhaps the concept of "component controllers" can be replaced with normal controllers the render an alternative view based on a "request context". This would open the doors for the Html.RenderComponet method to take a bool, that turns it into an ajax request from the rendered output on the clientside.
