Flash AMFPHP:Can'；t将PHP类映射到AS3类

我正在使用AMFPHP 1.9、ActionScript 3和带Flash player 10x的Adobe Flash Pro CS5。我试图通过调用amfphp服务获取数据。我正在Flash IDE中运行应用程序

对于字符串或整数之类的基本类型，它可以正常工作。但当尝试获取自定义对象时，会显示以下错误：

安全性错误：错误#2000:没有活动的安全上下文。

结果处理程序函数中的参数包含null。我错过什么了吗？请帮忙

以下是我的课程：

        {
            registerClassAlias("com.ddr.cv.model.Scene", com.ddr.cv.model.Scene) ;
        }
}

下面是Scene.php

    <?php
class Scene {

    var $id;
    var $sceneName;
    var $imageName;
    var $sceneCategoryID;
    var $userID;
    var $creationDate;

    // explicit actionscript package
    var $_explicitType = "com.ddr.cv.model.Scene";

    function Scene($id = 0, $sceneName = null, $imageName = null, $sceneCategoryID = 0, $userID = null, $creationDate = null)
    {
        $this->id = $id;
        $this->sceneName = $sceneName;
        $this->imageName = $imageName;
        $this->sceneCategoryID = $sceneCategoryID;
        $this->userID = $userID;
        $this->creationDate = $creationDate;
    }

    function getSceneByID($id){
        //creating dummy Scene object
        $scene = new Scene(1, "Test Scene", "test_scene.jpg", 6, null, null);
        return $scene;
    }

    function saveScene($scene)
    {
        //To Do:
    }
}
?>

处理程序：

var sceneService:SceneService = new SceneService();
sceneService.getSceneByID(1, getSceneByID_resultHandler, getSceneByID_faultHandler);

    public function getSceneByID_resultHandler(scene:com.ddr.cv.model.Scene):void
    {
        //scene contains null here.
        //Shouldn't it contain the dummy Scene object from amfphp service method?
        trace("Success: " + scene);
    }

    public function getSceneByID_faultHandler(fault:Object):void
    {
        trace(">>> fault:" + fault.description);
    }

@daidai:非常感谢您的回复。我原以为这篇文章会永远深藏在SOF数据库中，无人应答/无人回复，永远看不见曙光。然后，在漫长的10天后，你回答说：）我增加了你的答案，因为你想回答。再次感谢

我也在浏览器上测试过。同样的结果

但我终于明白了为什么几天前它不起作用。问题是，出于某种奇怪（或安全性）的原因，从MovieClip继承的自定义AS3类（我猜对于所有系统类来说）无法从它们的PHP对应项（在我的例子中是从Scene.PHP类）映射。 但是AS3类可以发送到PHP服务类并成功映射。 为了解决这个问题，我不得不对我的体系结构进行一些更改，并解决了我的问题。但这个问题真的让我很紧张，我把这篇文章每小时看几天，希望能得到回复

无论如何，我只在Flash player版本10.1.82.76上测试了它。我不知道它在以前的版本中是否有效，因为我没有对它们进行测试。
