Flex アプリケーションで、ターゲット オブジェクトを「文字列」に保存する方法を見つけました。
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

protected function button1_clickHandler(event:MouseEvent):void
{
var fr:FileReference = new FileReference();
var ba:ByteArray = new ByteArray();
ba.writeObject(container);
fr.save(ba);
}
]]>
</fx:Script>
<s:BorderContainer id="container" x="68" y="64" width="341" height="257">
<s:Label x="69" y="83" width="257" height="124" text="Label"/>
</s:BorderContainer>
<s:Button x="68" y="329" label="SAVE" click="button1_clickHandler(event)"/>
そのファイルを読み取って、AIR で UIComponent として表示する方法はありますか?
これは私の試みです:

そして、私はこのエラーが発生しています:

どんな解決策でも問題ありません...それが機能する限り:)
