Help with "attaching" variables to objects

programming flash
1

Not sure that attach is the correct name for this.

What I am trying to do is set variables associated with objects and then access those variables from a class file. But I am getting an “undefined” error.

The highlited code below shows where I am trying to group 2 radio buttons.


function handleParameters(file:Object):void
{ 
 /***** Set up the drop-down menu. ************************/
 var mcAttribute1:mcAttributes = new mcAttributes();
 mcAttribute1.name="mcAttribute1";
 mcAttribute1.x=mcAttribute1.y=16;
 mcAttribute1.comboAttribute.prompt="Choose";
 mcAttribute1.comboAttribute.addItem({label:" ", data:.1});
 mcAttribute1.comboAttribute.addItem({label:"0", data:0});
 mcAttribute1.comboAttribute.addItem({label:"1", data:1});
 mcAttribute1.comboAttribute.addItem({label:"2", data:2});
 mcAttribute1.comboAttribute.addItem({label:"3", data:3});
 mcAttribute1.comboAttribute.addItem({label:"4", data:4});
 mcAttribute1.comboAttribute.selectedIndex = 0;
 mcAttribute1.btnSubmitFile.addEventListener(MouseEvent.CLICK, handleSubmitFile);
 
[COLOR=darkred]var radBackTrack:RadioButtonGroup = new RadioButtonGroup("rbgBack");[/COLOR]
[COLOR=darkred]mcAttribute1.btnBackTrackTrue.group = radBackTrack;[/COLOR]
[COLOR=darkred]mcAttribute1.btnBackTrackFalse.group = radBackTrack;[/COLOR]
 this.addChild(mcAttribute1);
 
 /***** Set the focus to the text field. ************************************************************/
 stage.focus = mcAttribute1.txtAttFileName;
 mcAttribute1.txtAttFileName.setSelection(mcAttribute1.txtAttFileName.text.length,mcAttribute1.txtAttFileName.text.length);
 
 //mcAttribute1.txtAttMainText.restrict = "a-fA-F0-9";
 function handleSubmitFile(evt:Event):void
 {
  handleCheckDuplicate(mcAttribute1.txtAttFileName.text);
  var numberChoices:uint = mcAttribute1.comboAttribute.selectedItem.data;
 
  if (mcAttribute1.txtAttFileName.text != "" && mcAttribute1.comboAttribute.selectedIndex != 0 && duplicateFlag != true)
  {
   txtErrors.text = "";
   var fileHeight:int = file.height;
   file.txtFileName.text = file.name = mcAttribute1.txtAttFileName.text;
   fileInventory.push(file.name);
 
   var mcFileTarget1:mcFileTarget = new mcFileTarget();
   mcFileTarget1.x= file.width/2;
   mcFileTarget1.y = -2;
   mcFileTarget1.addEventListener(MouseEvent.MOUSE_UP, drawFinish);
   file.addChild(mcFileTarget1);
 
   for(var i:uint = 0; i<numberChoices; i++)
   {
    var mcChoiceTarget2:mcChoiceTarget = new mcChoiceTarget();
    mcChoiceTarget2.x= (file.width/numberChoices * i) + (5) + (3 * i) ;
    mcChoiceTarget2.y = fileHeight;
    mcChoiceTarget2.label = "choice"+(i+1);
    mcChoiceTarget2.addEventListener(MouseEvent.MOUSE_DOWN, drawStart);
    file.addChild(mcChoiceTarget2);
   } 
 
   file.tracking = new mapTarget(file);
 
   removeChild(getChildByName("mcAttribute1"));
  } 
 }
}

Here is my class file where I try to access the radio buttons. But I guess they are not there.


 
package classes
{
 import flash.display.MovieClip;
 import flash.text.TextField;
 import flash.events.MouseEvent;
 import flash.utils.Dictionary;
 import fl.controls.RadioButtonGroup;
 public class mapTarget extends MovieClip
 {
  public var choiceMap:Dictionary = new Dictionary();
  public var fileRef:Object;
  public var backTrack:Boolean;
  public function mapTarget(file:Object)
  {
   fileRef=file;
  }
  public function captureData(fileChosen:Object, choiceMapRef:Object):void
  {
   choiceMap[choiceMapRef]=[choiceMapRef.label,fileChosen.name];
   for (var prop:* in choiceMap)
   {
    trace(choiceMap[prop]);
   }
   trace("");
  }
  public function mapDataToXML():void
  {
   for (var prop:* in choiceMap)
   {
    [COLOR=darkred]trace(fileRef.radBackTrack.selection.label);[/COLOR]
[COLOR=darkred]    if (fileRef.mcAttribute1.radBackTrack.selection.label == "True")[/COLOR]
[COLOR=darkred]    {[/COLOR]
[COLOR=darkred]     trace("It's True!");[/COLOR]
[COLOR=darkred]    }[/COLOR]
[COLOR=darkred]    else if (fileRef.mcAttribute1.radBackTrack.selection.label == "False")[/COLOR]
[COLOR=darkred]    {[/COLOR]
[COLOR=darkred]     trace("It must be false!");[/COLOR]
[COLOR=darkred]    }[/COLOR]
   }
   trace("");
  }
 }
}
