jsf - Nested b:repeat - second repeat always the same -

i want render nested 2-level navigation using model file. navigation can change.

there simple bean navigationitem contains title, target, icon , list of possible sub items.

the navigation created simple:

@viewscoped @named public class navigation implements serializable  {      private list<navigationitem> navigation = new arraylist<>();      public list<navigationitem> getvalues() {         if (navigation == null || navigation.size() <= 0) {             navigationitem nava = new navigationitem("a", "icon-gauge", "site_a");             {                 list<navigationitem> subnav = new arraylist<>();                 subnav.add(new navigationitem("1", "", "subsite_1"));                 subnav.add(new navigationitem("2", "", "subsite_2"));                 subnav.add(new navigationitem("3", "", "subsite_3"));                 nava.setsubitems(subnav);             }              navigationitem navb = new navigationitem("b", "icon-layout", "site_b");             {                 list<navigationitem> subnav = new arraylist<>();                 subnav.add(new navigationitem("4", "", "subsite_4"));                 subnav.add(new navigationitem("5", "", "subsite_5"));                 navb.setsubitems(subnav);             }              navigationitem navc = new navigationitem("c", "icon-layout", "site_c");             {                 list<navigationitem> subnav = new arraylist<>();                 subnav.add(new navigationitem("6", "", "subsite_6"));                 navc.setsubitems(subnav);             }              navigation.add(nava);             navigation.add(navb);             navigation.add(navc);             navigation.add(new navigationitem("test", "icon-gauge", "site_d"));         }         return navigation;     }  } 

and here jsf

<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html" xmlns:f="http://xmlns.jcp.org/jsf/core" xmlns:b="http://butterfaces.org/components" >      <ul id="side-nav" class="main-menu navbar-collapse collapse">          <b:repeat value="#{navigation.values}" var="nav" rendered="true">             <li class="#{nav.hassubitems()==false ? '' : 'has-sub'}">                 <h:link outcome="#{nav.target}">                     <i class="#{nav.icon}"></i>                     <span class="title">#{nav.title}</span>                 </h:link>                  <ui:fragment rendered="#{nav.hassubitems()}">                     <ul class="nav collapse">                         <b:repeat value="#{nav.subitems}" var="subnav" rendered="true">                             <li>                                 <h:link outcome="#{subnav.target}">                                     <span class="title">#{subnav.title}</span>                                 </h:link>                             </li>                         </b:repeat>                     </ul>                 </ui:fragment>              </li>         </b:repeat>     </ul>  </ui:composition> 

my expected result:

• a
  • 1
  • 2
  • 3
• b
  • 4
  • 5
• c
  • 6
• d

my actual result is:

• a
  • 1
  • 2
  • 3
• b
  • 1
  • 2
  • 3
• c
  • 1
  • 2
  • 3
• d
