PrimeFaces中的BreadCrumb标签不起作用

Question

i am not able to call the action method from p:breadCrumb which is dynamically created... means when i cliked on p:menuitem in the breadcrumb it wont call my back() method in ManagedBean

and we are using primefaces3.4-snapshot jar

here my .xhtml

 <p:breadCrumb>
      <c:forEach items="#{pc_statusWiseRep.stackBeans}" var="path">
           <p:menuitem value="#{path.name}"  action="#{pc_statusWiseRep.backpath.id,path.lvl,path.name,path.slno}" update="form" />                                                 
     </c:forEach>
 </p:breadCrumb>

here is the method of back() in managed bean(session scoped)

public String back(String id, String lvl, String name, String slno) {
.....
}

List<StackBean> stackBeans = new ArrayList<StackBean>();

this is bean

public class StackBean {
String lvl = "";
String id = "";
String name = "";
int slno = 0;
..setters//getters
}

Please help Thanks in advance

It looks like you forgot to invoke the back method in your bean (see my changes in action ):

<p:breadCrumb>
      <c:forEach items="#{pc_statusWiseRep.stackBeans}" var="path">
           <p:menuitem value="#{path.name}"  
                       action="#{pc_statusWiseRep.back(path.id,path.lvl,path.name,path.slno)}" update="form" />                                                 
     </c:forEach>
 </p:breadCrumb>
