动态创建<rich:panelMenuGroup>和<rich:panelMenuItem>
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 styleiconCollapsedGroup="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>
