    Default Problem migrating from extjs 5 to extjs 6.5.2

    Hi, i'm working on django app, with ExtJS 5 on frontend part and trying to migrate to ExtJS 6.5.2. Extjs is connected via link, in templates, to app.js.

    With ExtJS 6 there's problem. When i'm running Django project, in browser console it throws exception: Uncaught TypeError: Cannot read property 'other' of undefined. It tries to read property 'other' of 'Ext.Boot.browserNames', but 'browserNames' is 'undefined'. Also 'Ext.Boot' is empty object.

    App works fine in development mode. I checked in console that 'Ext.Boot' is actually not empty object. And 'Ext.Boot.browserNames' is defined. So, problem arising only when i run my Django project.

    Default

    Well, best solution i found so far is to copy Ext.Boot definition from ext-all-debug.js file to my index.html
