Not able to use attribute of location field as default column?

[emaddoma]

Expected behavior

Display attribute of field as defautlt column. Keystone v3 supported this.

Actual/Current behavior

This no longer works in Keystone 4.

Steps to reproduce the actual/current behavior

`'use strict';

const keystone = require('keystone');

const Types = keystone.Field.Types;

/**

• Event Location Model
• ====================
  */

const EventLocation = new keystone.List('EventLocation', {
map: { name: 'location.name' },
track: true

});

EventLocation.add({
location: {
type: Types.Location,
enableMapsAPI: true,
initial: true,
collapse: false
}
});

EventLocation.defaultColumns = 'location.name, location.suburb, location.state';
EventLocation.register();
`
