GroupModel range filter errors when setting a group column filter to null

[CharlestonGeek]

I understand why the grouped column can't be filtered by null.

I am looking for documentation on how to prevent the range filter on a grouped column from allowing a null selection in the first place.

Something like:

Code: [Select]

minCheck = 1;
OR when null keep the range selection open until something is selected

On the attached image, Year is grouped. If you attempt to filter to 1 year, you might click deselect all. Which results in null and the following error.

Here is the error.

Uncaught TypeError: Cannot read properties of undefined (reading 'refresh')

Range filter allows deselect all in a grouped column without any error.

Please check ShipCountry and Customer Name columns in this example: https://paramquery.com/pro/demos/group_rows

When you add the filter range to the column it DOES NOT work. Only in the menuIcon.

Code: [Select]

    $(function () {
        var colM = [
            { title: "ShipCountry", width: 120, dataIndx: "ShipCountry", filter: { crules: [{ condition: 'range' }], gridOptions: { numberCell: {show: false} } } },
            { title: "Customer Name", width: 130, dataIndx: "ContactName", filter: { crules: [{ condition: 'range' }], gridOptions: { numberCell: {show: false} } } },
            { title: "Freight", width: 120, format: '$##,###.00',

                    type: "sum"
                },
                dataType: "float", dataIndx: "Freight", filter: { crules: [{ condition: 'range' }], gridOptions: { numberCell: {show: false} } }

Any confirmation or help?

The filter header range option/selecting is broken when rows are grouped.

I'm able to reproduce the error, moving it to bug report for further analysis, thanks for pointing out the issue.
