Access to object in xmlns

Question

Hi,
I've come across such a silly probem shown in example below:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:views="*" creationComplete="initApp()">
    <mx:Script>
        <![CDATA[
     import mx.controls.Text;
     public function initApp()
      label1.text = "View1 changed";
     ]]>
    </mx:Script>
    <views:view1 label="view1" width="100%" />
</mx:Application>
view1.xml file contains:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="100%">
<mx:Label id="label1" x="10" y="50" text="View1"/>
</mx:Canvas>
It renders error:
1120: Access of undefined property label1.
How can I access label1 object from main file?

Answer 1

Next I wanted to call function declared in main app:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:views="*">
    <mx:Script>
        <![CDATA[
        import mx.controls.Button;
     public function test():void
     ]]>
    </mx:Script>
    <views:view1 id="myComp" />
</mx:Application>
view1.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="100%">
<mx:Button id="button1" label="Button1" click="test()"/>
</mx:Canvas>
1180: Call to a possibly undefined method test.    ViewStackTest/src    view1.mxml    line 3    1251498782218    1661
How can reference to test()?
