To retrieve a value from the main application to the popup window

[prowannabe]

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:Script>
<![CDATA[
import mx.managers.PopUpManager;
public var helpWindow:Object;

public function displayForm():void {
// Array with data for the custom control ComboBox control.
var doctypes:Array = ["*.as", "*.mxml", "*.swc"]

// Create the pop-up and cast the return value of the createPopUp()
// Method to the ArrayEntryForm custom component.
var pop1:ArrayEntryForm = ArrayEntryForm(
PopUpManager.createPopUp(this, ArrayEntryForm, true));
// Set TitleWindow properties.
pop1.title="Select File Type";
pop1.showCloseButton=true;

// Set properties of the ArrayEntryForm custom component.
pop1.targetComponent = ti1;
pop1.myArray = doctypes;
PopUpManager.centerPopUp(pop1);
}

]]>
</mx:Script>

<mx:VBox>
<mx:TextInput id="ti1" text=""/>
</mx:VBox>
<mx:Button id="b1" label="Select File Type" click="displayForm();"/>
</mx:Application>

The following custom component, ArrayEntryForm.mxml, declares two variables. The first one is for the Array that the parent application passes to the pop-up window. The second holds a reference to the parent application's TextInput control. The component uses that reference to update the parent application:

<?xml version="1.0"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml"
showCloseButton="true" width="200" close="removeMe();" borderAlpha="1">

<mx:Script>
<![CDATA[
import mx.controls.TextInput;
import mx.managers.PopUpManager;

// Variables whose values are set by the main application.
// Data provider array for the component's ComboBox control.
[Bindable]
public var myArray:Array;
// A reference to the TextInput control in which to put the result.
public var targetComponent:TextInput;

// OK button click event listener.
// Sets the target component in the application to the
// selected ComboBox item value.
private function submitData():void {
targetComponent.text = String(cb1.selectedItem);
removeMe();
}

// Cancel button click event listener.
private function removeMe():void {
PopUpManager.removePopUp(this);
}
]]>
</mx:Script>

<mx:ComboBox id="cb1" dataProvider="{myArray}"/>
<mx:HBox>
<mx:Button label="OK" click="submitData();"/>
<mx:Button label="Cancel" click="removeMe();"/>
</mx:HBox>

</mx:TitleWindow>



If I interpret right that the above coding is what the user want to retrieve value from a combo Box from popup window to its main application.

But what should i do if i wanted to parse a value of the selectedItem value from a TileList item to a popup window with jus a SWF value which i will reference its source with my path + the value of the selectedItem from the tileList Item.

I wanted to try setting a variable from the main application and den parse that value to the popup window but could someone show me an example how to pass ?
