How do i change an array based on another text field? - actionscript-3

Question

i have a TheList.as class..in which i have created a list for an android app.
Here is TheList.as(Cut down to the specific stuff for this question)
public var _ListItem:ListItem;
public var _Data:Array;
public var _Values:Array;
public var $CurrentValue:String;
public var _TextLabel:TextField;
public function TheList(Data:Array,Values:Array)
{
_Data = Data;
_Values = Values;
initialize();
}
private function initialize():void
{
_TextLabel = new TextField();
addChild(_TextLabel);
_TextLabel.text = "Data";
_Container = new ListContainer ;
addChild(_Container);
_Container.x = 0;
_Container.y = 0;
currentY = _Container.y;
lastY = _Container.y;
for (var i:int = 0; i < _Data.length; i++)
{
_ListItem = new ListItem ;
_Container.addChild(_ListItem);
_ListItem.y = _ListItem.height * i;
_ListItem.addEventListener(MouseEvent.MOUSE_DOWN,onItemDown,false,0,true);
_ListItem.addEventListener(MouseEvent.MOUSE_UP,onItemUp,false,0,true);
_ListItem.mouseChildren = false;
_ListItem.value = _Values[i];
_ListItem.name = _Data[i];
_ListItem.ItemLabel.text = _ListItem.name ;
}
}
Here is the class "TheList" is being used in (Again Cut Down to specific stuff)
$myList = new TheList($Data,$Values);
addChild($myList);
$myList.x = -240;
$myList.y = -203;
$myList.visible = false;
$ListFrom = new TheList($DataFromTo, $ValuesFromTo);
addChild($ListFrom);
$ListFrom.x = -240;
$ListFrom.y = -203;
$ListFrom.visible = false;
$ListFrom._TextLabel.text = $DataFromTo[0];
$ListTo = new TheList($DataFromTo, $ValuesFromTo);
addChild($ListTo);
$ListTo.x = -240;
$ListTo.y = -203;
$ListTo.visible = false;
$ListTo._TextLabel.text = $DataFromTo[0];
Now what i am trying to achieve is that i want to change "$Data" and "$Values" Arrays..as you can see i have a main list and two sublists... when "Time" is selected in the main list, i want the sub-lists to be populated with "Time" related unit names...i tried
if($myList._TextLabel.text == "Time")
{
$ListFrom._Data = ["this", "this", "this" etc]
}
But its not working. I am not getting any error either. I'd really appreciate any help!

What you try to achieve is not pissible in this way. You initialize you lists with data fields. When you reset the data, you need to invalidate your list again. You can achieve this with an item setter
private var __Data:Array;
public function get _Data():Array
{
return __Data;
}
public function set _Data(value:Array):void
{
this.__Data = value;
initialize();
}
make sure that you first cleanup you list before you rebuild it again.
your code:
$ListFrom._Data = ["this", "this", "this" etc]
will automaticly call the setter. A getter and setter method looks like a function but is invoked like a property. means:
object.property = "something" //will call the setter
var something:String = object.property //will call the getter
