I have succeeded with adding localize files and ajax requests before lanuch of the application and in development a loadmask before launch is accepted and shows correctly but after production build I get an error that says that Ext.Viewport is undefined.
So my question is what I can do to show this loadmask before the launch or before all the other files (stores, models, controllers and views) initiates?
And what is the correct way to add a loader of an appication that loads data?
I don't need an single line answer with the line "I't wont work". Please elaborate what I can do.
