Renderer of CheckColumn subclass does not have widgets param

[ghulamghousdev]

It worked fine in a 5.6.5 but it does not work in 5.6.6.

Hi,

We've just upgraded our Grid from 5.6.2 to 5.6.6. Upon upgrade, we've noticed that our custom CheckColumn throws an error when trying to access the widget:

Cannot read properties of undefined (reading '0')

This can be replicated using the following code:

import { Toast, Grid, DataGenerator, CheckColumn, ColumnStore, StringHelper } from '../../build/grid.module.js?474079';
import shared from '../_shared/shared.module.js?474079';

class CustomCheckColumn extends CheckColumn {
    static type = 'customCheck';

static get defaults() {
    return {
         maxWidth: 50,
         resizable: false
    };
}

renderer({ widgets }) {
    widgets[0].disabled = true;
}
}

ColumnStore.registerColumnType(CustomCheckColumn);

new Grid({

appendTo : 'container',

columns : [
    { type : 'rownumber' },
    {
        text     : 'Template',
        minWidth : 160,
        flex     : 1,
        field    : 'name',
        type     : 'template',
        template : data => StringHelper.xss`Hi ${data.record.name}!`,
        // Cheaper measuring when sizing to fit content
        fitMode  : 'value',
        editor   : {
            label : 'Name'
        }
    },
    {
        text  : 'Custom rendering',
        width : 150,
        type  : 'customCheck'
    },
    { text : 'Date', field : 'start', width : 130, type : 'date', format : 'MMMM D YYYY' },

],

data : DataGenerator.generateData({
    count     : 50,
    addSkills : 3
})
});

This change broke it: https://github.com/bryntum/bryntum-suite/pull/8610/files#diff-456d5e452e3556323274889ba481b703396766616ec7ce7b0d8e9b3ff657d742L168

@isglass can you remember why it went from

me.renderer = me.internalRenderer;

to

me.setData('renderer', me.internalRenderer);
