Unanswered: Not a true offline application?
Hey so I want to make my application be able to be used when there is no internet. I have built my application through build production. "sencha app build production". All my data has been stored in local storage, and if I turn off the internet and do not close my application the application runs and "seems" like it is running offline. Uh let me explain a little more, I open my application on the ipad in the browser than I do add to home screen. So the scenario i speak of is when the app is "on the ipad". If i close the application and restart it in offline mode it will say "Could not be opened because it is not connected to the internet". How can i bypass this? Any tips?

Have you validated that all your required resources, plug-ins and files are available in your offline environment, if you use the dynamic loading of Sencha components...it will fail in off-line mode.

Offline Data Caching
I have a production build of an app that is hosted on a web server and can be navigated to using the iPhone's browser. When a user "Adds to Homescreen" is it possible to have the app launch and display cached content when the device is in airplane mode?
I have tried launching it from the homescreen when not in airplane mode (the content displays correctly), and then launching it again with airplane mode activated, and no luck: the device tells me I have to be connected to the internet to even launch the app.
I have seen the discussions about using a cache manifest. I will look into that now, but I would like to know if I need to cache all of the app files, or just the files that are not part of the basic Sencha Touch 2 framework.
Thanks for any help in advance.

If you move your app into a Sencha Cmd-based project, a cache-manifest file will be automatically generated when you issue a "sencha app build" directive. Note that you may need to configure your web server to send a mime type of type of "text/cache-manifest" for files with a .appcache file extension. See the following URL for more details:
