    Default Javascript error when click on disabled column menu in grid header

    Hi Mark,
    to disable grid headers menu I use columnMenu={null} as reported by docs.
    However if I click on arrows in the grid header I receive an error in browser console:
    Code:
    Error: [Ext.create] Invalid class name or alias 'undefined' specified, must be a non-empty string
    A simple example to reproduce error:
    Code:
    import React, { Component } from 'react'
    import { Grid, Column } from '@extjs/ext-react';
    
    export default class MyExample extends Component {
    
        store = new Ext.data.Store({
            data: [
                { "name": "Lisa", "email": "[email protected]", "phone": "555-111-1224" },
                { "name": "Bart", "email": "[email protected]", "phone": "555-222-1234" },
                { "name": "Homer", "email": "[email protected]", "phone": "555-222-1244" },
                { "name": "Marge", "email": "[email protected]", "phone": "555-222-1254" }
            ]
        });
    
        render() {
            return (
                <Grid store={this.store} columnMenu={null}>
                    <Column text="Name" dataIndex="name" flex="1"/>
                    <Column text="Email" dataIndex="email" flex="1"/>
                    <Column text="Phone" dataIndex="phone" flex="1"/>
                </Grid>
            )
        }
    }
