    rich:tree stateAdvisor: java.lang.ClassCastException

      Good afternoon.

      I can't understand the reason of this exception...

      I have WAR and JAR in one EAR, deployed on the server. If I put DepartmentTreeStateAdvisor class in my WAR's package - everything works perfectly. But if only I move it in my JAR's package - I got this exception: java.lang.ClassCastException: netinfo.hrdslr.tree.DepartmentTreeStateAdvisor


      I have netinfo.hrdslr.tree package in JAR, there are DepartmentTreeNode and PostbackPhaseListener classes. And I just can't add here and DepartmentTreeStateAdvisor, because of that exception.

      By the way - all my other action methods I use with richFaces are in the bean, which is in JAR, not in WAR. And everything works. The exception is only rich:tree with DepartmentTreeStateAdvisor...

      Why?

      Thanks in advance!


      P.S.: For sure I always change faces-config.xml when moving DepartmentTreeStateAdvisor from one package to another.

      P.P.S.: departmentTreeStateAdvisor is in my application variables as: netinfo.hrdslr.tree.DepartmentTreeStateAdvisor@13be7c0


      Here is my tree:

      <h:form id="employeesDataTable_form">

 <rich:tree style="width:250px" styleClass="tree" switchType="ajax"
 ajaxSubmitSelection="true" showConnectingLines="true" toggleOnClick="true"
 stateAdvisor="#{departmentTreeStateAdvisor}" changeExpandListener="#{amBean.onDepartmentTreeExpand}">
 <rich:recursiveTreeNodesAdaptor roots="#{amBean.departmentsTreeRoots}" var="item" nodes="#{item.nodes}" />
 </rich:tree>

 </h:form>



      Here is my exception stack trace:
