Question about child "windows"

Question

Hello Everyone,
First, I want to thank everyone who's so graciously taken
their time to answer my previous questions. Because of you, I am
well on my way to developing my very first real world Flex
application. I am consistently astounded at how helpful this
community is and am very thankful to have you all here.
Now, I do have one question about some code that works on the
example but not in real life. I am trying to open a popup window
from a class named composeScreen. In my CDATA section, I have the
following code:
function showWindow(modal) {
var popup = mx.managers.PopUpManager.createPopUp(this,
composeNewMessage, modal, {deferred: true});
Yet, when I save the program, Flex Builder tells me:
"Access of undefined property mx"
Any idea why this is happening?
I've even tried importing the mx.managers.popUpManager class
and it makes no difference.
Please help! This is driving me nuts!
Thanks in Advance,
Anthony

Hi Anthony,
You will have to use popup manager class for this.Here is the
code to give you a lil bit of direction. Call init() function in
the initilize event of the <mx: application> tag
import mx.managers.PopUpManager;
private function init():void{
myWindow = PopUpManager.createPopUp(this, MyWindow, false);
myWindow.visible = false;
myWindow.x = 200;
myWindow.y = 200;
myWindow.height = 100;
private function showWindow():void{
myWindow.visible = true;
myWindow.expand.play();
<mx:Button id="btn" label="click me"
click="showWindow()"/>
When you click on the button your child window must pop
up.
