css - ZK 错误 UI 组件

Question

我在 apache 中部署 ZK 时出错，

 java.lang.ClassCastException: neraca.neracaController cannot be cast
 to org.zkoss.zk.ui.util.Composer
    org.zkoss.zk.ui.metainfo.ComponentInfo.toComposer(ComponentInfo.java:410)
    org.zkoss.zk.ui.metainfo.ComponentInfo.toComposer(ComponentInfo.java:397)
    org.zkoss.zk.ui.metainfo.ComponentInfo.toComposers(ComponentInfo.java:365)
    continued...

这是我的 zul 文件，

我猜应用标签有错误，但我不确定，我已经更改了它但错误仍然发生，请任何人帮助我:)

Answer 1

您的 java 类 neraca.neracaController 是什么样的？它必须从 GenericForwardComposer 扩展。如果是，则应该没有问题。

public class NeracaController extends GenericForwardComposer {
    ...
}
