We are using facelets. i have have tried it a couple different ways, but here
is a snippet with Jstl c:if and below it a snippet with rendered. When the page
is first rendered the navbars display or hide correctly. When I come back to
the page, even if the bean value is changed the components don't update:
<c:if test ="#{navigation.tabNavigationAllowed}">
<ul>
<c:set var="billingCenter" value="#{lbls.billingAction}" />
<c:choose>
<c:when test="#{tabSelected == 'billingCenter'}">
<li class="firstselected">
<a tabindex="1" jsfc="h:commandLink"
value="#{lbls.billingLabel}" actionListener="#{navigation.generalAction}"
action="#{navigation.getAction}" immediate="${immediate}"
id="#{lbls.billingAction}" ></a>
</li>
</c:when>
<c:otherwise>
<li>
<a jsfc="h:commandLink"
value="#{lbls.billingLabel}" actionListener="#{navigation.generalAction}"
action="#{navigation.getAction}" immediate="${immediate}"
id="#{lbls.billingAction}" ></a>
</li>
</c:otherwise>
</c:choose>
</c:if>
<h:outputText rendered="#{navigation.tabNavigationAllowed}">
<li class="firstselected">
<a tabindex="1" jsfc="h:commandLink" value="#{lbls.billingLabel}"
actionListener="{navigation.generalAction}" action="#{navigation.getAction}"
immediate="${immediate}" id="#{lbls.billingAction}"></a>
</li>
</h:outputText>
Thanks!
