Well glad to hear the debugging is progressing.
The app loading indicator seems like a strange issue. You could create just a skeleton application, which would contain the app loading indicator, and I suspect it should work. Have you customized the app loading indicator otherwise?
Not sure I understand your config.xml issue, but that seems more webworks related than sencha. Have you searched the bb developer forums for a solution for that?
Yeah I'll investigate about the appLoadingIndicator bug after fixing everything else, but I haven't modify that part of the code, the only thing I know is when I let the CSS the application crash, if I remove it, it works.
Maybe a conflict with some JS? It would be weird but porting application to BB is full of surpise :)
Yeah I'll check with them directly the config.xml error.
Thanks again for all your support :)
Checking the conflict should be easy enough - if you rename the CSS class and update the div tag and it works, then you know it was a conflict.
You may also want to check the app.js. There is a reference via Ext.fly that accesses the div to remove it. Maybe it's crashing there?
