Hi Aral,
This doesn't look like a bug to me.
You are effectively creating a sub-class with the same class members as its
base class contains (set the keep-generated flag when you compile and you'll
see that) and the Flex compiler is correctly warning you of that.
Taking MXML out of the equation (and simplified), here's what you're really
doing:
class com.ariaware.pizza.view.Application extends mx.core.Application
{
...
private var orderForm:OrderForm;
...
class AprPizza extends com.ariaware.pizza.view.Application
{
...
public var orderForm:OrderForm;
...
So, you are hiding the base class member.
Is there really a need to have the same class members in both the base class
and the sub-class? If you explain what you're trying to do, we may be able
to offer alternatives.
Cheers,
Ali

Subject: [flexcoders] Bug report: Incorrect hidden member in ancestor class
warnings
Hi all,
Sorry I haven't had the chance to report this sooner but it appears that
Flex issues incorrect warnings when you extend the core Application and/or
Form classes and try to reference a component both in MXML and AS.
Case in point:
// ArpPizza.mxml
<pizzaView:Application
xmlns:pizzaView="com.ariaware.pizza.view.*"
xmlns:mxml="*"
xmlns:mx="http://www.macromedia.com/2003/mxml";
backgroundImage="@Embed('Graphics/design.gif')"
// ...
>
<mx:Canvas width="550" height="400">
<mx:LinkBar id="linkBar" x="360" y="14" />
<mx:ViewStack id="screens" x="38" y="59">
<mxml:OrderForm id="orderForm" label="Order Form" />
<mxml:ViewOrdersForm id="viewOrdersForm" label="View Orders" />
</mx:ViewStack>
// ...
Note: ViewStack contains the two forms with ids set to orderForm and
viewOrdersForm.
class com.ariaware.pizza.view.Application extends mx.core.Application {
//
// On stage
//
private var screens:mx.containers.ViewStack;
private var linkBar:mx.containers.LinkBar;
private var orderForm:OrderForm;
private var viewOrdersForm:ViewOrdersForm;
private var dataPreloader:ProgressBar;
// etc.
* * *
Actual behavior:
4 Warnings found.
Warning /ArpPizza.mxml:22
The member, viewOrdersForm, hides a member in ancestor class,
'com.ariaware.pizza.view.Application'.
Warning /ArpPizza.mxml:21
The member, orderForm, hides a member in ancestor class,
'com.ariaware.pizza.view.Application'.
Warning /ArpPizza.mxml:22
The member, viewOrdersForm, hides a member in ancestor class,
'com.ariaware.pizza.view.Application'.
Warning /ArpPizza.mxml:21 The member, orderForm, hides a member in ancestor
class, 'com.ariaware.pizza.view.Application'.
* * *
Expected behavior: No warnings should be given as we are not hiding a member
(we are simply referring to the same member, once in MXML and once in AS2.)
This is exactly what we do in Flash when we give a component an instance
name and then declare it in the form's class.
I know the Flex MM team frequent this forum so I thought I'd send this over
here. If you need the full app to test with, just let me know.
Thanks,
Aral
