Order by Date

I have problems to make the order per date. Grilla order by the day without taking into account the month.

You have to set date format for this column -

var myText = [
  ["10-May-05"],
  ["2-Jun-06"],
  ["30-Aug-04"]
];

    var date = new AW.Formats.Date;
    date.setTextFormat("d-mmm-yy");

    var obj = new AW.UI.Grid;
    obj.setCellText(myText);
    obj.setCellFormat(date, 0);

    obj.setColumnCount(1);
    obj.setRowCount(3);

    document.write(obj);
