Oops spoke too soon. I'm getting a TypeError: Error #1009: Cannot
access a property or method of a null object reference when I click on
the datagrid to send the ID. The code hasn't changed since the example
below, but I'm not sure how to troubleshoot this one.
public function onSelectFirstGrid(event:Event):void
{
orgProgramRequest.addEventListener(Event.COMPLETE,
onResult)
//var params:Object = new Object();
//params['id'] = dgOrg.selectedItem.orgID;
orgProgramRequest.send(dgOrg.selectedItem.orgID);
}
public function onResult(e:ResultEvent):void
{
var xmlResult:XML = e.result as XML;
trace(xmlResult.toXMLString()); //is that the xml you
expected?
var xlResult:XMLList = xmlResult.children(); //or other
expression
trace(xlResult.length()); //is that the right
expression?
dg2data = new XMLListCollection(xlResult)
trace(dg2data.getItemAt(0).toXMLString());
}
[Bindable]
public var dg2data: XMLListCollection;
