I finally got around to a major overhaul of the CFQueryReader site, including all new demos and documentation of the latest build for Ext JS 4.x.
The new demos for Ext JS 2.x and 3.x include links to legacy API's for both versions of the library. The 3.x version includes an example of using Ext Direct, and the new 4.x demo includes paging data grids.
(Big thanks to Loiane's Ext JS 4 First Look, which showed me very quickly how dead simple Ext JS grids and data stores have become.)
I have not yet tested CFQueryReader with Sencha Touch, but it should work. Any feedback just let me know.
