Deselecting options with multiple: true raises TypeError: cannot read property 'query' of null

[muhammadarsal]

I'm defining my column for multiple select2 like this:

{
    name: "location",
    label: "Location",
    cell: Backgrid.Extension.Select2Cell.extend({
        multiple: true,
        optionValues: [["Boston", 1], ["Greater Boston Area", 2], ["Alto", 3]]
    })
}

When the cell goes in edit mode selected option show just fine. But when I click on 'x' to deselect an option, console goes red with:

Uncaught TypeError: Cannot read property 'query' of null
