[flexcoders] How come datagrid shows nothing ?

[maylam18]

Hi Everyone,

How come nothing show up in the datagrid? Please help.

How come LINE XXX shows nothing?

LINE KKK generates the following xml document:

<GetDialectsResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns="http://FaciNet.com/"; 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
  <GetDialectsResult>
    <Dialect>
      <ValueID>1</ValueID>
      <Description>English (Canada)</Description>
    </Dialect>
    <Dialect>
      <ValueID>2</ValueID>
      <Description>Spanish (Mexico)</Description>
    </Dialect>
    <Dialect>
      <ValueID>3</ValueID>
      <Description>Spanish (Honduras)</Description>
    </Dialect>
    <Dialect>
      <ValueID>4</ValueID>
      <Description>Portuguese (Brazil)</Description>
    </Dialect>
    <Dialect>
      <ValueID>5</ValueID>
      <Description>Turkish (Turkey)</Description>
    </Dialect>
  </GetDialectsResult>
</GetDialectsResponse>

The flex 2 code is shown below:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; 
layout="vertical" creationComplete="WS.GetDialects.send()">

 [Bindable]private var _xmlResult:XML;
 [Bindable]private var _myXmlList:XMLList;


 private function resultHandler(event:ResultEvent):void {  
                
        _xmlResult = XML(event.result); //converts result Object to 
XML. can also use "as" operator
        trace(_xmlResult.toXMLString()); // LINE KKK
        
        
        var xlMyListData:XMLList = _xmlResult.Dialect; 
        _xlcMyListData = new XMLListCollection(xlMyListData); 
        trace(_xlcMyListData.toXMLString()); // LINE XXX
