QueryPosition="below" for MX:Combobox

[onnut]

I have combobox that populate by dataprovider.

var search_Planname:mx.controls.ComboBox = search_Planname;
responseHandler.GetPlanName_Result = function( results: Object ):Void {
//when results are back, populate the cfselect
search_Planname.labelField = "Planname";
search_Planname.dataProvider = results;
}
I want to have "Select All" option as the first option in the combobox. I tried using QueryPosition but it doesnt work.
Thanks.
