RichFaces rich:panelMenu stops working when a4j:include'd

From this previously asked question, I have noticed that when I move a rich:panelMenu (which works fine when in an index.jsp page) into another.jsp and then include that in index.jsp using an a4j:include tag, the rich:panelMenu functionality stops working.

Is this a bug?

EDIT 1

In response to code and after some isolation testing, the problem appears to stem from a coexistence of a rich:dataTable in another tab of a rich:tabPanel from the panelMenu.

If my index.jsp contains a default simple panelMenu using demo code (inc in the bean) it works as expected:

<f:view>
    <rich:page pageTitle="title" markupType="xhtml">
        <h:outputText id="setup" value="#{MyBacking.setup}" />
        <rich:toolBar height="35" itemSeparator="line">
            <rich:toolBarGroup location="left">
                <a4j:form>
                    <a4j:outputPanel id="panel">
                        <h:outputText style="text-align: center" value="Node Select " />
                        <h:selectOneMenu id="nodes" value="#{MyBacking.chosenNode}">
                            <f:selectItems value="#{MyBacking.nodes}" />
                        </h:selectOneMenu>
                        <a4j:commandButton value="Retrieve"
                            reRender="开发者_StackOverflow中文版panel,contentPanel"
                            onclick="this.disabled=true" oncomplete="this.disabled=false" />
                    </a4j:outputPanel>
                </a4j:form>
            </rich:toolBarGroup>
        </rich:toolBar>
<!-- added start -->
        <h:form id="form">
            <h:panelGrid columns="2" width="100%">
                <rich:panelMenu style="width:200px" mode="ajax"
                    iconExpandedGroup="disc" iconCollapsedGroup="disc"
                    iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right"
                    iconCollapsedTopGroup="chevronDown">
                    <rich:panelMenuGroup label="Group 1">
                        <rich:panelMenuItem label="Item 1.1"
                            action="#{PanelMenu.updateCurrent}">
                            <f:param name="current" value="Item 1.1" />
                        </rich:panelMenuItem>
                    </rich:panelMenuGroup>
                </rich:panelMenu>
                <rich:panel bodyClass="rich-laguna-panel-no-header">
                    <a4j:outputPanel ajaxRendered="true">
                        <h:outputText value="||#{PanelMenu.current}|| selected"
                            id="current" />
                    </a4j:outputPanel>
                </rich:panel>
            </h:panelGrid>
        </h:form>
<!-- added end -->
        <rich:panel>
            <h:panelGroup layout="block" id="contentPanel">
                <a4j:include viewId="#{MyBacking.viewId}">
                    <f:param name="targetIdParam" value="content" />
                </a4j:include>
            </h:panelGroup>
        </rich:panel>
    </rich:page>
</f:view>

But if I remove the added panelMenu from this file and paste it into a separate tab in a tabPanel in an external jsp page which is then a4j:included in the above index.jsp, when it's loaded, the panelMenu refuses to work (outputting nothing to the log or console) while in the other tab in my tab set there is a rich:dataTable. With the exact same code, but with the dataTable removed from the second tab, it all starts working again.

Here's the broken a4j:included file with panelMenu:

<h:panelGrid columns="1" border="0" style="width: 100%">
    <rich:tabPanel switchType="client" rendered="true">
        <rich:tab styleClass="tab" label="Node Logs">
            <h:panelGrid columns="2" border="0">
                <h:graphicImage value="/btn50.png" width="30" height="30"
                    alt="Logs" />
                <h:outputText value="log: #{MyBacking.chosenNode}"
                    styleClass="pageTitle" />
            </h:panelGrid>

            <h:form id="form">
                <h:panelGrid columns="2" width="100%">
                    <rich:panelMenu style="width:200px" mode="ajax"
                        iconExpandedGroup="disc" iconCollapsedGroup="disc"
                        iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right"
                        iconCollapsedTopGroup="chevronDown">
                        <rich:panelMenuGroup label="Group 1">
                            <rich:panelMenuItem label="Item 1.1"
                                action="#{PanelMenu.updateCurrent}">
                                <f:param name="current" value="Item 1.1" />
                            </rich:panelMenuItem>
                        </rich:panelMenuGroup>
                    </rich:panelMenu>
                    <rich:panel bodyClass="rich-laguna-panel-no-header">
                        <a4j:outputPanel ajaxRendered="true">
                            <h:outputText value="||#{PanelMenu.current}|| selected"
                                id="current" />
                        </a4j:outputPanel>
                    </rich:panel>
                </h:panelGrid>
            </h:form>

        </rich:tab>

        <rich:tab styleClass="tab" label="Docs">
            <rich:dataTable value="#{MyBacking.MyData}">
                <rich:column style="text-align:center" width="150px">
                </rich:column>
            </rich:dataTable>
        </rich:tab>
    </rich:tabPanel>
</h:panelGrid>

Thanks

This problem went away when I recast the taglib declarations as

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:a4j="http://richfaces.org/a4j"
    xmlns:rich="http://richfaces.org/rich">

instead of using <% %> tags (which aren't used with facelets anyway)

and installed jsf-facelets-1.1.14.jar. No facelets jar was installed at all until this point!
