Issue with jstl + facelets

[Julien Martin]

Hello,

I am trying to obtain a dynamic menu. I have the following xhtml facelets pages:

menu.xhtml

<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:pretty="http://ocpsoft.com/prettyfaces"
                xmlns:c="http://java.sun.com/jsp/jstl/core">
<ul>
        <!-- accueil -->
        <c:choose>
            <c:when test="#{page==accueil}">
<li id="active"><a  id="current" rel="nofollow"><h:outputText value="#{msg['menu.accueil']}" /></a></li>
            </c:when>
            <c:otherwise>
<li><pretty:link id="accueil" mappingId="rootAction"><f:param value="#{view.locale.language}"/><h:outputText value="#{msg['menu.accueil']}" /></pretty:link></li>
            </c:otherwise>
        </c:choose>
        <!-- galerie -->

        </c:choose>
        <!-- commandes personnalisées -->
        <c:choose>
            <c:when test="#{page==commandesPersonnalisees}">
<li id="active"><a id="current"  rel="nofollow"><h:outputText value="#{msg['menu.commandes-personnalisees']}" /></a></li>
            </c:when>
            <c:otherwise>
<li><pretty:link id="commandes-personnalisees" mappingId="commandesPersonnaliseesAction"><f:param value="#{view.locale.language}"/><h:outputText value="#{msg['menu.commandes-personnalisees']}" /></pretty:link></li>
            </c:otherwise>
        </c:choose>
        <!-- contact -->
        <c:choose>

            </c:otherwise>
        </c:choose>
        <!-- liens -->
        <c:choose>
            <c:when test="#{page==liens}">
<li id="active"><a  id="current" rel="nofollow"><h:outputText value="#{msg['menu.liens']}" /></a></li>
            </c:when>
            <c:otherwise>
<li><pretty:link id="liens" mappingId="liensAction"><f:param value="#{view.locale.language}"/><h:outputText value="#{msg['menu.liens']}" /></pretty:link></li>
            </c:otherwise>
        </c:choose>
</ul>
</ui:composition>

and in my home page:

 <ui:include src="WEB-INF/include/menu.xhtml">
       <ui:param name="page" value="accueil"/>
 </ui:include>

The unexpected result is as follows: the contents of both <c:when... and ><c:otherwise is displayed!!!

Can anyone please help?

Thanks in advance,

J.>

JSTL does not work well with JSF, facelets or not.

There are some very nice JSF Menu components out there, however. For example: http://livedemo.exadel.com/richfaces-demo/richfaces/dropDownMenu.jsf

Thanks Tim,
I eventually found a solution: that is using the <h:panelGroup with only the rendered attribute. Thus I have no ><span or ><div in my html.

Actually, I recommend little or no actual HTML. JSF tags can generally do everything you need. Sometimes it can be a little awkward, but you'll be in better shape in case you need to adapt the app for a non-HTML platform some day.
