@Don Douthitt - Sorry this blog eats up code pretty badly. I tried your example using ActionScript and I see the same results as MXML. Are you sure you are using the owner property in both cases? If you have a small sample application that demonstrates what you are seeing I can investigate further if you send me the source: steve at flexponential.

Well, my mxml was eaten. It’s a TextArea with an ID of “mxml_ta” inside a SkinnableContainer.

My tests show the owner tree is different if components are added dynamically in actionscript instead of through mxml. For example, the following code…

private function onCreationComplete():void {
var container:SkinnableContainer = new SkinnableContainer();
var ta:TextArea = new TextArea();
ta.text = “Test Message.”;

container.addElement(ta);
this.addElement(container);
}

… produced this “owner” tree:
++++: Test
+++: SkinnableContainer
++: SkinnableContainerSkin
+: contentGroup
: TextArea

This MXML code, however…

… produced a different “owner” tree:
++: Test
+: SkinnableContainer
: mxml_ta

Is this expected?

Thanks.

This is very helpful! I did not realize the difference between owner and parent but this example really helps out.

Interesting! Thanks for the post. I think I’ll be using the ‘owner’ property to climb the DisplayList from now on, since it seems it filters out a lot of unnecessary things such as skins etc.
