[flexcoders] probably-stupid AS3 question

2006-05-19 Thread Josh Santangelo 



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

Oh, morning, my EYES!

I see you casted it but to the SellerEdit's superclass which does not hold seller only SellerEdit does not TItleWindow.


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

or


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

Hi,

Simple casting problem;


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

to

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

RE: [flexcoders] probably-stupid AS3 question

2006-05-19 Thread Gordon Smith 



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));
