      Hi,

       

      i'm trying to build a dynamic tree in my jsf web apps. and i used rich faces.

      i took an example from the rich faces live demo and try it in my page .. the tree appear fine.

      but when i click on any node the following exception appear :

       

      java.lang.IllegalArgumentException: In AbstractTreeDataModel rowIndex must be -1.

      actually on any submission in the page the above exception is thrown.

       

       

      the code in jsp page :

      ------------------------------------------------------------------------------------

      <f:view>
          <h:form>
                                             
              <rich:tree id="accountsTreee" style="width:300px"  rendered="true"
                  nodeSelectListener="#{accountsChartIterators.processSelection}"
                    reRender="selectedNode" ajaxSubmitSelection="true"  switchType="client"
                    value="#{accountsChartIterators.treeNode}" var="item" ajaxKeys="#{null}"  >              
              </rich:tree>                                    
          </h:form>                                
      </f:view>

      ------------------------------------------------------------------------------------

       

       

      and the bean code :

                  }
              }
          }

       

      public void processSelection(NodeSelectedEvent event) {
