jQuery Grid Plugin - jqGrid

I am using the 3.7.2 version

From the documentation on beforeSaveCell:

applies only to a cell that is editable; this event fires before validation of values if any. This event can return the new value which value can replace the edited one
beforeSaveCell : function(rowid,celname,value,iRow,iCol) {
if( some_condition )
{ return “new value”; }
}
The value will be replaced with “new value”

From grid.celledit.js in the saveCell function:

[skipped some code]

case "select":
    if(!cm.editoptions.multiple) {
        v = $("#"+iRow+"_"+nmjq+">option:selected",$t.rows[iRow]).val();
        v2 = $("#"+iRow+"_"+nmjq+">option:selected",$t.rows[iRow]).text();
    } else {
        var sel = $("#"+iRow+"_"+nmjq,$t.rows[iRow]), selectedText = [];
        v = $(sel).val();
        if(v) { v.join(",");} else { v=""; }
        $("option:selected",sel).each(
            function(i,selected){
                selectedText[i] = $(selected).text();
            }
        );
        v2 = selectedText.join(",");
    }
    if(cm.formatter) { v2 = v; }
    break;

[skipped some code]

if ($.isFunction($t.p.beforeSaveCell)) {
    var vv = $t.p.beforeSaveCell($t.rows[iRow].id,nm, v, iRow,iCol);
    if (vv) {v = vv;}
}

[skipped some code]

if ($t.p.cellsubmit == 'clientArray') {
    $(cc).empty();
    $($t).jqGrid("setCell",$t.rows[iRow].id,iCol, v2, false, false, true);
    $(cc).addClass("dirty-cell");
    $($t.rows[iRow]).addClass("edited");
    if ($.isFunction($t.p.afterSaveCell)) {
        $t.p.afterSaveCell($t.rows[iRow].id,nm, v, iRow,iCol);
    }
    $t.p.savedRow.splice(0,1);
}

I am in the callback event for a cell with an edittype = 'select' and a custom formatter.

On the red bold line above, the code is calling setCell with v2 which is the original value from the select and not v which is the value from my callback function.

So the return from the beforeSaveCell callback is being ignored.

I think v2 needs to be replaced with the value in v in the call to setCell.
