Dynamic Tree and TreeNode Issue

Question

I am using JSC2 (060120) on Win2K pro, exporting the WAR and running in JBoss 4.0.3 running under JDK 1.5.0_04.
I am trying to dynamically build a tree as the user clicks on nodes and am not having success following the example at http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/sitemaptree.html
When I attempt to add the child nodes directly to nodes via clickedNode.getChildren().add(myNewNode); I get an error as follows:
10:17:29,260 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
javax.faces.el.ReferenceSyntaxException: AP-1030Child.id
at com.sun.faces.application.ApplicationImpl.checkSyntax(ApplicationImpl.java:749)
at com.sun.faces.application.ApplicationImpl.createValueBinding(ApplicationImpl.java:291)
The ID shown AP-1030Child.id does not exist, my to be parent node is named AP-1030 and my to be child is named AP-1030-Bottom.
The only way I can get the Tree to build properly is to add the to be child (AP-1030-Bottom) to the Tree itself and then assign it's parent as the node (AP-1030). But, the problem I run into then is the next time the parent node (AP-1030) is clicked parent.getChildCount() or parent.getChildren().size() both evaluate to zero and I attempt to build the children for the node at which point the code blows up due to duplicate naming.
Has anyone else experienced this? Am I doing something wrong?
Here is the code I use to build my tree initially on the SessionBean...
for(int i = 0; i < count; i++)
TreeNode newNode = new TreeNode();
newNode.setId("AP-" + pages.pageId);
newNode.setText(pages[i].page);
newNode.setImageURL("/resources/tree_document.gif");
MethodBinding nodeMethodBinding = this.getApplication().createMethodBinding("#{MainPage.treeNode_action}", null);
newNode.setAction(nodeMethodBinding);
this.applicationPagesTree.getChildren().add(newNode);
Here is the code I am using to add the child nodes to the clicked node...
     for(int l = 0; l < locationsCount; l++) {                               
          TreeNode locationNode = new TreeNode();
String sectionText = "";
          (populate sectionText with Top|Left|Center|Right|Bottom based on data)
          locationNode.setText(sectionText);
          // making unique name for this object in the tree: parentname + section
locationNode.setId(searchID + "-" + sectionText);
locationNode.setImageURL("/resources/tree_document.gif");
          // bind to method for the page sections click
MethodBinding nodeMethodBinding = this.getApplication().createMethodBinding("#{MainPage.locationNode_action}", null);           locationNode.setAction(nodeMethodBinding);
          // adding to the base tree object after the parent (why can I just not add to the node?)
          this.treeList.getChildren().add(insertIndex + l, locationNode);
          // this nudges the node over one, otherwise it is peer to the parent (again, why not just add to the parent?)
locationNode.setParent(node);
Why is it I can get the String ID from the tree and not the object? Wouldn't it make sense to give me the TreeNode instead of it's ID when calling getCookieSelectedTreeNode()? This would seem a more proper object orientated approach.
Any help appreciated, thanks.

Thanks,
I have tried pretty much that exact same code and it does not work for some reason. That code is the same as the example I showed that I followed originally.
The only way I can get it to work is as I showed. When I do the node creation and then add to the node in the tree it blows up while rendering with the message from the original post.
