How to access component's control property from main .mxml file

Question

I have a main .mxml while in which i imported custom
"popUpWindow" component using "import component.popUpWindow"
statement. In main .mxml file I display later on that component as
popUp window using popUp manager class. Once component is
displayed, how can i access using actionscript component's
TextInput control (specifically its .text property) from my main
.mxml file?
thanks

I posted this answer elsewhere, maybe it will help:
First, save the new component wherever you keep your
components, let's say you call it "MyPopWindow.mxml"
Assign public variables for the string in both the main app
and the popup.
In your case, in the main app:
Code:
public var myText:String = "whatever the text field should
say.";
and then in the pop up mxml:
Code:
[Bindable]
public var myText;
Then, in the main mxml file:
Code:
// define the window type
private var popWin:MyPopWindow;
private function popMeUp(event:MouseEvent):void{
popWin =MyPopWindow(PopUpManager.createPopUp(this,
MyPopWindow, true));
popWin.myText = myText;
The important things here to notice is the name of the
component (i.e. the file) is used. A variable is created for the
window, and TYPED to your file name. Then you use the constructor
you already had, but again use your type. The "true" is optional
and gives you a modal popup window.
Lastly, assign the variable in the window (I called mine
popWin) to the variable in the main file you want to pass.
