I'm having a similiar problem to the original poster's post. I am developing in Sencha Touch 2.0 preview version. I have a docked toolbar which is displayed at the top and a scrollable list. The docked toolbar displays fine, but the list doesn't appear on my android browser. I even tried installing other webkit browsers in my android (Ultralight Browser, Ninesky Browser) and I get the same results - the list doesn't appear.
However, my list does appear on my PC-Google Chrome and PC-Safari.
so the results of my testings so far:
Google Chrome(PC) - works fine
Safari(PC) - works fine
iPhone(Safari) - works fine
Android(chrome) - LIST IF NOT DISPLAYED
Android(any webkit browser) - LIST IS NOT BEING DISPLAYED
