RE: [flexcoders] probably-stupid AS3 question

You don't show how you declared __editWindow, but from the error message
it sounds like you declared it as

    var __editWindow:TitleWindow;

The problem is that Adobe's TitleWindow class doesn't have a "seller"
property; it's your SellerEdit subclass of TitleWindow that added that
property.

When you create an MXML component SellerEdit.mxml starting with
<mx:TitleWindow>, the MXML compiler autogenerates a subclass that looks
like

    public class SellerEdit extends TitleWindow
    {
        public var seller:Object;
    }

So the solution is to declare

    var __editWindow:SellerEdit;

and cast the result of createPopUp() to a SellerEdit:

    __editWindow = SellerEdit(PopUpManager.createPopUp(this, SellerEdit,
true));

Subject: [flexcoders] probably-stupid AS3 question

I'm new here, as will be made clear by the beginner-level of my
question...

I have a TitleWindow component in SellerEdit.mxml:

<mx:TitleWindow ... >
      <mx:Script>
            <![CDATA[
                  public var seller:Object;
            ]]>
      </mx:Script>
</mx:TitleWindow>

And from my application, I create it:

__editWindow = TitleWindow(PopUpManager.createPopUp(this, SellerEdit,
true));
__editWindow.title = 'Edit Seller';
__editWindow.addEventListener('creationComplete', initWindow);
__editWindow.seller = sellers.selectedItem;

I get an error on the last line, "Access of possibly undefined property
seller through a reference with static type mx.containers:TitleWindow."

According to the "Defining properties and methods in ActionScript"
article in help, it sounds like this is the right way to do it? Am I
just missing something obvious?

thanks,
-josh
