Thanks Sean. I guess I did misunderstand your point. I have looked at the source for dataTable a little and did find it usefull for fixing a different problem that I was having. I'll dig in to it more to see if I can come up with something.
It's a shame that they didn't make the dataTable more flexible to begin with. I'll keep trying. I'm not giving up on myFaces and JSF.
