In the popup, you would do:
<mx:Text text="{_app.myBindablePublicVar}" ./>
Here is a full example. In it, I passed in a reference to the mainApp
instead of using the Application.application reference.

Hi Tracey,
Your comment in your first reply is exactly what I'm asking clarification
on:
>From 1st reply...
" Now you can bind to any bindable property in MyMainAppFileName"
How would you do this?
Sorry if it's really simple but I can't work out how to databind in as3 to a
dynamically created popup.
Thanks.

See the code in my first reply.

Hi Tracey,
Many thanks for your responses so far.
My only question is how do you bind any data into the popup?
Some example code...
In the parent AS code:
// declare new instance of my popup item
Var addPopUP:MyPopUp = new MyPopUp();
// assign var value to popup
AddPopUp.someData = _someData;
// display popup
PopUpManager.addPopUP( addPopUp, this, true);
In the Popup:
[Bindable]
Private var _someData:String;
[Bindable]
Public function set someData (value:String):void
{
_someData = value;
}
Public function get someData():String
{
return _someData;
}
So, with your code inserted, how would the code above look different so that
when the _someData var in the parent changed, popup would automatically see
that change? (without creating another function in the parent - it needs to
be binded).
Thanks!
Dave.

".in the creationComplete="init() of the PopUp?" Yes.
Full syntax of what? This: "[Bindable]private var _app:MyMainAppFileName;"
is full syntax.

Tracy:
What do you mean by?
In a creation complete handler, assign:
_var =Application.application as MyMainAppFileName;
Do you mean in the creationComplete="init() of the PopUp? If so, what is the
full syntax?
Thanks!
