在尝试将 RichFaces 与 OpenFaces 合并到树表中时，它不显示任何展开折叠按钮。原来有些js没有加载，可能是这个原因。

JSF代码如下：

<o:treeTable var="o">
                        <o:dynamicTreeStructure nodeChildren="#{bean.originNodeChildren}"
                                                nodeHasChildren="#{bean.originHasChildren()}"/>
                        <o:treeColumn expandedToggleImageUrl="/img/toggle-expand-light.png"
                                      collapsedToggleImageUrl="img/toggle-collapse-light.png">
                            <h:outputText value="#{o.description}"/>
                        </o:treeColumn>
                    </o:treeTable>

Bean 代码被正确触发（包括 hasChildren 方法）。

JS 异常：

使用OpenFaces 2.0 版和 RichFaces 3.3.3 版。

需要在 web.xml 中为打开的面配置资源过滤器，工作就完成了。就像是：

public class OpenFacesResourceFilter extends ResourceFilter {
    // -- Fields --

    // -- Methods --
    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        try{
            super.doFilter(servletRequest, servletResponse, filterChain);
        } catch (ServletException e) {
            Throwable parent = e.getCause();
            if(parent!=null && parent instanceof ServletException) {
                throw (ServletException) parent;
            } else {
                throw e;
            }
        }
    }
}

看起来您确实没有在应用程序的 xml 文件中声明 OpenFaces 资源过滤器。以下是有关如何声明过滤器的文档的摘录（请注意，您不必自己为此过滤器创建任何 Java 类）：

  <!-- FILTER FOR PROCESSING INTERNAL OPENFACES RESOURCES -->
  <filter>
    <filter-name>ResourceFilter</filter-name>
    <filter-class>org.openfaces.util.ResourceFilter</filter-class>
  </filter>

  <!-- MAPPING FOR OPENFACES RESOURCE FILTER -->
  <filter-mapping>
    <filter-name>ResourceFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

请参阅 OpenFaces 2.0 文档中的安装部分和资源过滤器优化部分。
