GraniteDS 无法从 ActionScript 类转换为 Java bean...如何解决这个问题？

Question

我有一个Entity bean，它是相应的ActionScript类，当我传输该类的对象时，我得到了这个错误：

请帮忙？？？提前致谢 ：）

Answer 1

我有这样的问题。
就我而言，使用模块时会发生这种情况。

所以我需要在我的主应用程序中预加载特定的类。

在 Main.mxml 上：

private var loadClasses:Array = [Funcionario, Cliente, Projeto];

Answer 2

从你的例外情况来看……

Caused by: org.granite.messaging.amf.io.convert.NoConverterFoundException:
Cannot convert: com.xpress.spt.beans.SptStatus@760dac
to: java.util.Set<com.xpress.spt.beans.SptStatusHist>

我猜你在 SptStatus 和 Set 之间存在类型冲突。

Answer 3

我们在枚举方面也遇到了这个问题。通过最近升级花岗岩解决了这个问题。这取决于你把花岗岩罐子放在哪里。如果在 jboss/server/default/lib 中，您可能会遇到此错误。如果您的项目中不应该出现花岗岩.jar。不管怎样，对花岗岩罐子进行一次新的更新......
