select all checkboxes of a rich tree node

[cravi]

Hey guys,

I know that this is a well discussed topic but I didn't find a satisfing solution.

So at the moment my page is showing a rich tree with two levels. Each of its nodes contains a checkbox and a output text.

The issue is after selecting the checkbox of a parent node, all children checkboxes should be also selected. In the opposite if a parent node is unselected all children checkboxes should be unselected too.

The main problem for me is to get access to the checkboxes of the children nodes. I can only get the TreenNodeImpl of the nodes but these don't contain the checkboxes.

I tried to use an instance of UITree or HTMLTree to walk down the nodes to the children but same problem I can only get the TreeNodeImpl and no checkboxes.

Hope someone understands my problem and has an idea.

Here are parts of the source code:

{code}<rich:tree id="mainTree" switchType="client" toggleOnClick="false" nodeFace="#{item.type}" value="#{TreeController.treeView}" 
                                 var="item" nodeSelectListener="#{TreeController.processSelection}" >
     <rich:treeNode iconLeaf="/images/form_General.png" id="node" icon="/images/form_General.png" type="PlainForm" >
          <h:panelGroup>
               <h:selectBooleanCheckbox value="#{item.selected}" id="cb" onchange="this.form.submit( );" 
                    valueChangeListener="#{TreeController.checkboxClick}" />
               <h:outputText value="#{item.name}" id="formNodeText" styleClass="exportTreeNodeText" />
          </h:panelGroup>
     </rich:treeNode>
</rich:tree>
{code}
