CommandLink is not in a jsf Form because i have added it to the template. However it is disabled. Is there an alternative way to enable it?

Since commandLink launch an action, you have to add a h:form

  <h:form>
 <h:commandLink action="#{welcomeBean.logOutSession}" class="subAnchor" value="Log Out"/>
 </h:form>

I have Added My commandLink (which is the logout link) into the template File which is not inside a jsf form.

MainTemplate.xhtml

<h:commandLink action="#{welcomeBean.logOutSession}" class="subAnchor" value="Log Out">
</h:commandLink>

on the webpage that uses the template, i have all the elements inside a jsf form:

NewWelcome.xhtml

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
                 xmlns:h="http://xmlns.jcp.org/jsf/html"
                 xmlns:f="http://xmlns.jcp.org/jsf/core"
                 xmlns:ui="http://java.sun.com/jsf/facelets"
                 template="/webpages/templates/MainTemplate.xhtml">

  <ui:define name="infomationPartOfBody">
     <h:form>
<div>  Here i have all the page specific content </div>

 </h:form>
 </ui:define>

 </ui:composition>

I was hoping that the logout would work once i use the template in a page with a jsf form. However, the logout commandLink shows error :

Log Out: This link is disabled as it is not nested within a JSF form.

I know a clear solution is to add this element separately into each of the xhtml pages that would use the template. But i want it to be added into the template itself as it is a common element in all the pages.

Any help would be deeply appreciated. Thank You! :)

Editing: here is the code of my MainTemplate.xhtml

user3489875 about 10 years

Did you try this: <li><h:form> <h:commandLink action="#{welcomeBean.logOutSession}" class="subAnchor" value="Log Out"/> </h:form></li>
