Multiple Selection in rich:tree

[pavelv]

Hi everyone!

In my application I need to have ability for multiple selection in rich tree.

I found this article

http://technology.amis.nl/blog/4710/multi-select-in-richfaces-trees

I tried to do this but nothing works. My tree has client switch type.

When my jsp looks like this:

     <f:view>
     <h:form>
          <rich:panel header="RichFaces Tree Test" style="width: 600px">
               <rich:tree style="width:300px"
                    nodeSelectListener="#{simpleTreeBean.processSelection}"
                    reRender="selectedNode" ajaxSubmitSelection="true"
                    switchType="client" value="#{simpleTreeBean.treeNode}" var="item"
                    ajaxKeys="#{null}">
                    <rich:treeNode id="node" nodeClass="#{item.selected?'dr-tree-i-sel':''}">
                        <h:outputText value="#{item.nodeTitle}"/>
                    </rich:treeNode>
               </rich:tree>

          </rich:panel>
          <h:outputText escape="false" value="Selected Node: #{simpleTreeBean.nodeTitle}" id="selectedNode" />
     </h:form>
     </f:view>

miltiselection doesn't work at all.

But if I add node to tree reRenderer

reRender="selectedNode, node"

Then I get error during node selection:

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

but after page refresh clicked nodes are selected.

Can you help to solve my problem?
