问题：

javax.faces.facesException：不能将同一个组件添加两次:javascript_runner

盛城
2023-03-14

我用WildFly、Java8和ICEfaces 4.0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,但如果单击任何组件,则会出现以下错误：

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，如果不删除它，我还会遇到其他错误（“ConfigurationException：来自namespace http://xmlns.jcp.org/jsf/html的名为inputFile的标记有一个空处理程序类定义”）。
