Thanks for the response. But i'm not using a json file currently. In my version i just add the css file to a html file like so
<link rel="stylesheet" href="touch/resources/css/main.css" type="text/css">
it is working in sencha touch 2.0.1 but not in 2.1
if you are building css files from scss, make sure, that your "config.rb" has correct path to sdk folder. Note that now "sdk" folder is renamed to "touch", so you may have to fix that. Then compile your scss and try again...
that fixed a lot for me, but I admit, I still have some strange layouts (probably because different sencha theme css ), specially in lists that I changed from dataview (since now lists can have components).
