I've been banging my head around this for about 12 hours now and am not getting anywhere. I'd really appreciate some help or direction. I can't get a visualforce page to render a sense ExtJS tree panel with data from JSON. I'm using ExtJS 4.2.1.
(Note that I removed some fields and records, I can post the whole thing if it would be helpful).
I have a visualforce page to render the data but I can only get it to show the columns and nothing else. Below is my visualforce page.
<!-- Visualforce (using ExtJS) display/selection of Campaign hierarchy two ways by Jeff Trull ([email protected]) -->
<apex:page controller="VolunteerShiftControllerNew" tabstyle="Campaign">

I really don't know what I'm doing with Javascript and I'm sure I'm missing something silly. I do know that the data is getting to the visualforce page and as far as I can tell with the chrome javascript debugging tool it is at least making it into my results variable (res) but nothing gets rendered.
Please help! I promise I've done my due diligence on Google :).
