Does anyone have a simple example of an Ext.direct based TreeStore (with read and update api clauses instead of directFn) that uses CFQueryReader?

I'm having the hardest time trying to get my TreeGrid working correctly and just need to see a working example with CFQueryReader.

If anyone could provide the store & model config piece, plus the json being sent/recieved for a node lookup so that I can analyze, I'd be very grateful.
