Flex: TextInput Focus issues

1. add a initial function on Flex app

mx:application initialize="onLoad(event)"

...

import flash.external.ExternalInterface;


private function onLoad(event:Event):void {
ExternalInterface.call('setBrowserFocus');
this.myCanvas.setFocus();
}

2. add javascript "setBrowserFocus ()" into index.template.html

function setBrowserFocus(){

document.getElementById('${application}').focus();

}

3. test again.
