Hi, I started using the, what seems to be, more 'proper' method of deploying sencha touch apps:
"sencha app create" & "sencha app build".
Rather than simply including the script, sencha-touch-all.js.
I was interested in optimizing my app, getting it smaller and faster for deployment. Unfortunately, the switch caused several problems. Some tabs in one of the tabpanels no longer show. In a different one of my tabpanels one of the tabs does not show its card. All of my Ext.Panel's that are "modal: true" are not actually modal. I suspect I'm not doing the requires stuff correctly... because, as I said, I was earlier using sencha-touch-all.js when it worked the way I wanted.
Here is my app.js (app.coffee). Let me know what other code you need.
