Question

I started with https://github.com/mclin/extjs-mvc-example, and set out to modify it so that it used Ext.application, instead of just using Ext.Create() for a subclass of Ext.app.Application.

So far so good, until I try to use the getApplication() function, which isn’t there.

The code of the app definition looks like …

Ext.application({
   name: 'Books',
   extend: 'some.class.name',
   controllers: ['Books'],
   ...
});

The result of this is a global object named ‘Books’, alright, but it does not define getApplication(), contrary to the Ext documentation.

Answer 1

From memory getApplication was added after 4.1.1, 4.12 or 4.13 IIRC.

Also, you shouldn’t use extend with Ext.application().
