Hi Alex I.,
It seems there is a bug in the GridRatingColumn that prevents it from getting initialized in hierarchical tables. Our dev team fixed this bug immediately and you can find the fix applied in an upcoming Service Pack release of Telerik RadControls for ASP.NET AJAX. If this is urgent for you, you can also download tomorrows internal build, even though we do not recommend using internal builds in production projects.
As a token of gratitude for your contribution to the improvement of Telerik RadControls, I have updated your Telerik points with additional 500.
