动态创建和

使用<ui:repeat>和<rich:dataList>动态创建<rich:panelMenuGroup>和<rich:panelMenuItem>时都会抱错！所以使用了<c:forEach>。
环境：seam 2.1.1GA
     richfaces3.2.2.SR1

<rich:panelMenu   styleClass="menu" 
        iconExpandedGroup="disc" iconCollapsedGroup="disc"
        iconExpandedTopGroup="chevronUp" iconGroupTopPosition="left"
        iconCollapsedTopGroup="chevronDown" iconCollapsedTopPosition="left"
        >
        <c:forEach items="#{menuList.resultList}" var="menu">
            <rich:panelMenuGroup label="#{menu.name}" rendered="#{empty menu.menu}">
            <c:forEach items="#{menu.menus}" var="childMenu">
            <rich:panelMenuItem label="#{childMenu.name}"
                                action="#{childMenu.getAction()}">
            <s:conversationPropagation type="end"/>
            </rich:panelMenuItem>
            </c:forEach>
        </rich:panelMenuGroup>
        </c:forEach>
    </rich:panelMenu>
