jsf - PrimeFaces tabmenu not changing index -


i using p:tabmenu component. have 4 menuitems, each 1 redirects different jsf page problem page returned without changing activeindex , activeindex remains same initial value 0.

<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:p="http://primefaces.org/ui"> <p:tabmenu activeindex="0">     <p:menuitem value="home" url="menu.jsf" icon="ui-icon-star"/>       <p:menuitem value="fabricants" url="/pagess/pagesfabricant/fabricant.jsf" icon="ui-icon-wrench" />       <p:menuitem value="composants" url="/pagess/pagescomposant/composant.jsf" icon="ui-icon-search"/>       <p:menuitem value="dossier d'equivalence" url="deq.jsf" icon="ui-icon-document"/>   </p:tabmenu>   </ui:composition>

how can solve problem knowing should change automatically ?

you can use el set @ managed bean level. this

<p:tabmenu activeindex="#{mybean.myactiveindex}">     <p:menuitem value="home" url="menu.jsf" icon="ui-icon-star" action="#{mybean.setactiveindex(0)}"/>       <p:menuitem value="fabricants" url="/pagess/pagesfabricant/fabricant.jsf" action="#{mybean.setactiveindex(1)}" icon="ui-icon-wrench" />   </p:tabmenu>

Why does Ruby on Rails generate add a blank line to the end of a file? -
