I am a beginner in Flex. I downloaded FlashDevelop, created a new Flex 4 application and added a simple snippet of code to test whether it worked. As I understand it, the app should print out 'hello'. Instead, it does nothing - just a blank window with no output to debug log whatsoever.

The weird thing is that if i substitute <s:Application> for <mx:Application>, it prints 'hello' just fine. But then it doesn't display any elements from the namespace.

So I'm guessing this is a problem that has to do with Spark.

Current setup:

  • FlashDevelop 4.4.2
  • Compiling for SDK : Flex 4.6.0 and AIR 3.7 (I guess I'm not using AIR, though. And I even tried Flex 4.9.1, didn't work either)
  • I'm not including any libraries other than the default in FD

Main.mxml

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx"
               creationComplete="trace('hello');">

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
</s:Application>

我认为这可能是项目正在编译的 Flash Player 版本：为什么没有显示此图像？
