Unanswered: touch 2 app working from localhost but not from remote server
I'm working on my first Sencha Touch 2 app. I was originally programming it locally. So, I would call it up in a web browser using something like ... localhost/app. Everything works fine from localhost.
However, now I have a need to give other people a preview. So, I tarred up the app directory and put it on a webserver... I've created a trimmed down test version of it here... http://apps.thinkunderground.com/touchtest/
Now when I run it from the remote URL, and click the "try" button, an error occurs (in chrome)... Uncaught TypeError: Cannot call method 'destroy' of null
I do have that data being displayed in a dataview with a store that retrieves data via JSONP.
So, my question is, Am I packaging and relocating the app properly? and any idea why this would only be failing on a remote webserver and not on localhost?
