Alright, I have a tree that display a list of projects, and under each project a list of devices that belong to it. I need to have things change when a user clicks on a device or on a project. I have it to the point where if a user clicks on a project, it will do what I want. But when a user clicks on a device under the project I get this error:

WARNING: /disposable/test.xhtml @47,99 nodeSelectListener="#{treeClickBean.projectSelection}": java.lang.ClassCastException: java.lang.String cannot be cast to nodesContainer.ProjectHolder

I have a List of Objects bound to my rich:tree (the Object is called ProjectHolder). So for my rich tree I did this for the nodeSelectListener:

<rich:tree nodeSelectListener="#{treeClickBean.projectSelection}" reRender="selectedNode"
 switchType="client" ajaxSubmitSelection="true" ajaxKeys="#{null}">
 <rich:treeNodesAdaptor nodes="#{nodesBean.projects}" var="project">
 <rich:treeNode>
 <h:outputText value="#{project.projectName}" />
 </rich:treeNode>
 <rich:recursiveTreeNodesAdaptor roots="#{project.devicesList}" var="device">
 <rich:treeNode>
 <h:outputText value="#{device}" />
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
 </rich:treeNodesAdaptor>
 </rich:tree>

This calls the following method:

public void projectSelection(NodeSelectedEvent event){
 HtmlTree tree = (HtmlTree) event.getComponent();
 node = (ProjectHolder) tree.getRowData();
 name=node.getProjectId();
 }

And then I have a h:outputText to display the value of that name variable. So when a user clicks on the project, the projectId is displayed as intended.

But my problem is with when a user clicks on the device. If I do it as is, I get the error above saying cannot convert from String to ProjectHolder Object.

I tried adding a nodeSelectListener attribute to the device treeNode, that uses String values instead of the ProjectHolder Object but it does the same. I would like to find a way to just manipulate that java code, and leave the tree as is, with only the one nodeSelectListener attribute in the first rich:tree tag.

Oh and one other thing, this part of the tree:

<rich:recursiveTreeNodesAdaptor roots="#{project.devicesList}" var="device">
 <rich:treeNode>
 <h:outputText value="#{device}" />
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>

is actually referring to a List of devices, not just a String with one device.

So Im sure there is a way to manipulate that projectSelection() method above where it can tell the difference between clicking on the project name or one of the devices from the List right? I was looking at stuff like (this is incomplete btw):

selectedNodeChildren.clear();
 TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());
 if (currentNode.isLeaf()){
 selectedNodeChildren.add((String)currentNode.getData());
 }else
 {
 Iterator<Map.Entry<Object, TreeNode>> it = currentNode.getChildren();
 while (it!=null &&it.hasNext()) {
 Map.Entry<Object, TreeNode> entry = it.next();
 selectedNodeChildren.add(entry.getValue().getData().toString());
 }
 }

to add to the projectSelection method, but this has givem me no luck as of yet.

Can anyone please give me some guidance on this one?
