I believe that you need to import the valueObjects.ShoppingCartItem
component again from within your <Component> tags.
Do it within the VBox...
...
<mx:Component>
<mx:VBox>
<mx:Script>
<![CDATA[
import valueObjects.ShoppingCartItem
]]>
</mx:Script>
<mx:Button label="Remove"
click="outerDocument.removeItem(valueObjects.ShoppingCartItem(data));" />
</mx:VBox>
</mx:Component>
..etc
I'm reasonably sure that this has to do with using the outer document
as a reference.. the immediate component can't see what the outer
document sees (the import).
