Easy way to pull text file into Flex 3

Super easy!
Just call a service with GET and specify the resultFormat as text.

Then, in your script tag make a bindable variable and assign the value of the service call to the variable

   import mx.rpc.events.ResultEvent;
  import mx.rpc.events.FaultEvent;
  
  [Bindable]
  public var myTextVariable:String;
  
  public function txtHandler(event:ResultEvent):void
  {
   myTextVariable = myTextService.lastResult.toString();
  }
 ]]>

Then bind your variable to your text field

Finally, don't forget to call your service from your application tag.

creationComplete="myTextService.send()"
