I'm getting an error, while integrating React CoreUI Bootstrap project with ExtReact:

Uncaught TypeError: Cannot read property 'ClassManager' of undefined
at Object.<anonymous> (ExtJSComponent.js:97)

And that Object.anonymous line is in the file:

node_modules\@extjs\reactor\src\ExtJSComponent.js and looks like this:

    const Ext = window.Ext;

    var CLASS_CACHE = {
            Grid: Ext.ClassManager.getByAlias('widget.grid'),
            ...

And that's ALL I get.

Can someone please give me at least some directions if not the whole answer.

is ExtJSComponent file made by you ? – Tejas Apr 10 '18 at 09:48
@Tejas I get the same exception from this file so it isn't custom. See stack trace from OP. – hbulens Apr 10 '18 at 20:55
In [ExtReact](http://docs.sencha.com/extreact/6.5.0/modern/Ext.ClassManager.html) doc there is no method `Ext.ClassManager.getByAlias()` – Narendra Jadhav Apr 11 '18 at 05:55
