I have released an updated version of CFQueryReader, a custom Ext data reader for parsing the JSON that ColdFusion natively produces for it's query objects. This is complete re-write of this component, specifically for Ext JS 4.x (I have not tried it with SenchaTouch yet, but have been told it should work) using the new class model. Slimmer, trimmer, and immensely simplified, a developer can include the file and write some very basic configuration and it just works.
We have a completely new site, documenting the component, including examples for Ext JS 2.x, 3.x and the new component for 4.x. You can also follow the project on RIAForge and GitHub.
