Question

我使用WildFly，Java 8和ICEfaces 4.0.0在Maven中创建了一个项目。在Maven的pom.xml中，我添加了ICEfaces和ICEfaces-ACE依赖项。 ACE组件显示正确，但如果我单击任何组件，我会收到此错误：

这是我的build.xml。我已经从org.icefaces中排除了javax.faces，因为它附带了WildFly并且我得到了其他错误（“ConfigurationException：来自命名空间http://xmlns.jcp.org/jsf/html的名为inputFile的标记有一个null处理程序类定义”）如果我不知道删除它。
