In the following code, the call to myChild.bar() results in an exception because myChild is null. myParent is a valid object. What I don't understand is why myChild has not been created yet.

I have read the following document related to object creation sequence, but I am unsure how "new" is related: http://livedocs.adobe.com/flex/3/html/help.html?content=layoutperformance_03.html

Any help is appreciated!

// Main.mxml

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="created()">

        <![CDATA[
            public var myParent:Parent = new Parent();
            public function created():void {
                myParent.foo();
            }
        ]]>
    </mx:Script>
