Just going through the process of setting up an app for windows 8 mobile.
App prepared in Architect through Sencha version 2.2 and packaged through sendcha cmd. Using cordova 3.0.
It seems that adding a pull refresh to a list within Sencah has the effect of crashing the app (fails to load fully and end up on a blank screen) when it runs on a device, though it works fine in the browser preview. Tested only on Visual Studio Express 2012 emulator. If I take away any of my pull refresh list plugins, the app runs fine.
