I've never used Venkman. I gave it a try and it rules! I've been debugging with alert and MochiKit's log. Venkman is MUCH more pleasant.
I managed to get my response processed but I'm not getting scrollbars like I'm supposed to. My issue was that I needed to register an element with rico's ajaxEngine. The LiveGrid documentation specifically says you don't have to, but it lies. Or, I'm missing some other magic attribute somewhere.
