Last week I was trying to understand how datatables are rendered in 4.x as well. I would really like to see an explination of this as it was a major change in 4.x and the javadocs on the new classes are like UIDataAdaptor are almost more harm than help. The documentation on all the new datatable classes is very sparse, to the point it only beneifts someone who participated in the implementation. Any help in understanding the original question would be appreciated.
Should questions like this posted to the developer forum?
