I am not able to follow fully where you are in your function..
I don't see in this trail of messages where you make your DataGrid
call..
Here is what I do..
<mx:DataGrid id="hdGrid" dataProvider="{myHDData}"
alternatingItemColors="[#CCCCCC, #AAAAAA]" x="10" y="10"
change="switchit(event)">
public function switchit(event:Event):void {
var myLogdata:XMLList = new XMLList();
currentState = 'ticketdisplay';
if ( event.target.selectedItem.ticketname ) {
mName.text =
event.target.selectedItem.ticketname;
}
I have no problems...
