我将尽可能多地提供细节

我正在使用Flex（Cairngorm 2）/Java/Hibernate创建一个CRM应用程序。我面临的基本问题是：

我有一个Java中的Customer类，它有一个地址类的ArrayList。我在Flex中有一个Customer类，它有一个地址类的ArrayCollection

当我为客户进行远程对象调用时，我在Flex中得到一个客户对象，但是ArrayCollection对象的数据类型是object而不是Address

如果我尝试调用地址类列表，我会得到相同的结果。如果我尝试调用一个客户类列表，我会在Flex中得到一个客户类列表

你应该在SWF的某个地方找到你的

地址。最好的方法是在主应用程序中声明一个字段：
private var references:Object = {addressClass:Address, someOtheClass:SomeOtherClass};

问题是ActionScript中的ArrayCollection
没有类型引用（Java中的泛型）。所以类的字节码不包括在SWF中。Constantiner说得对，我们通常只在main中的on initialize方法中执行此操作。另一个地方是，即使您在代码中的某个地方引用了对象，但使用模块时，该对象不会被编译到应用程序中，并将作为对象出现。同样的补救方法也适用。如果我理解正确，我需要引用该类，以便在编译时包含它。我可以引用：public var address:address；或者我需要像上面那样做。两种方法都有效吗？我想我应该把这句话放在这里：两种方法都试过，但都没有乐趣。我知道我把它放在了正确的位置，因为当我动态创建视图时，我必须做一些类似的事情。这些都在编译中，所以我有了“public var newCustWin:CustomerForm；公共var findCustWin:FindCustomer；公共var测试：TestView//尝试此公共变量引用：对象={addressClass:Address}//这是一个单独的公共地址：address；'您可以使用查看真实的AMF数据。它显示了类映射。若数据传输正确，你们应该在客户端挖掘铲斗。在另一种情况下，问题出现在服务器端。我有一个Flex dump实用程序，可以转储对象，查看对象的所有内容，我在错误的位置查找。您的解决方案非常有效。谢谢你，两种方法都试过了，但都不高兴。我知道我把它放在了正确的位置，因为当我动态创建视图时，我必须做一些类似的事情。这些都在编译中，所以我有了“public var newCustWin:CustomerForm；公共var findCustWin:FindCustomer；公共var测试：TestView//尝试此公共变量引用：对象={addressClass:Address}//这是一个单独的公共地址：address；'
