Yeah, I think I remember now that we weren't happy with that pattern because under repeated refinements it results in long thin "strands" of pyramids? So we just never implemented it, but it's definitely possible there would be other changes needed in the library to do it, as it would be the only element with heterogeneous children... If anybody out there is thinking about it, it might be nice if the refinement pattern didn't include *any* pyramids at all! -- John ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
