[Dominique Bessette - Halsema]

Here is the code for the itemRenderer for a combobox i made.  The
dataProvider is xml.


<?xml version="1.0" encoding="utf-8"?>
<mx:ComboBox xmlns:mx="http://www.adobe.com/2006/mxml";
 rowCount="2" labelField="@name" dataProvider="{weemcStatus}"
change="onSelectionChange(event)">

            private var ownerData:XML;

            //binds the xml row data to the combobox and appends the
weemcStatus
            override public function set data(value:Object):void
            {
                if(value){
                    ownerData = value as XML;
                    if(ownerData.weemcStatus.toString() == "" ||
ownerData.weemcStatus.toString() == null){
                     var item:XML = <weemcStatus>WILCO</weemcStatus>;
                     ownerData.appendChild(item.toXMLString());

                    }
                }

            {

            override public function setFocus():void
            {
                super.setFocus();

                open();
            }
