I'm under the impression this is simply the nature of the "home screen" web apps that operate outside of normal Safari. I have an app that operates just fine in Safari with some minimal state saving, but the blasted non-Safari version refreshes every time. EDIT: Even the showcased O’Reilly example that uses a cache manifest reloads every time when added to the home screen.

You may want to look into creating "routes" (URL fragments) that point to a controller/action pair. Look into the MVC PhoneGap example (If not using PhoneGap, you can scroll past all of that stuff and implement your own data model and store). Also see this Sencha Touch MVC tutorial.

Also, most of the rendered sencha touch components seem to maintain state between changes of the active item. For example. I have a main TabPanel that contains all sub panels. When switching between tabs on the main TabPanel's TabBar, each sub panel maintains its rendering, unless I've set a listener or controller action to do otherwise.

Hope this helps.
