JTree Nodes with the same name

Question

What do I have to do to get the JTree to render nodes with the same name? These Nodes user objects are completely different object types and each has a unique hashcode.
+ Root Node
+-- node1 (this is a folder)
+-- node1 (this is a file)
The problem is I have n folders in my tree but if a parent folder contains a folder and a file with the same name then no other subfolders are displayed.
The nodes exist in memory because I enumerate the tree and display its contents in System.out.
Thanks in advance!

Thank you to everyone that responded. I solved the issue. It was a timing issue...here's my original method:
private void renderProductFolder(SubFolder sf){
try{
WTPart part = QueryHelper.service.findWTPart("number", sf.getNam());
WTTreeNode node = buildWTTreeNode(part);
super.getTreeModel().setRoot(node);
renderTree(node, sf); // This is the problem call
super.getSelectionModel().
setSelectionPath(new TreePath(node.getPath()));
super.expandPath(new TreePath(node.getPath()));
}catch(Exception ex){
ex.printStackTrace();
Here is the fix:
private void renderProductFolder(SubFolder sf){
try{
WTPart part = QueryHelper.service.findWTPart("number", sf.getNam());
WTTreeNode node = buildWTTreeNode(part);
renderTree(node, sf); // This was the problem call
super.getTreeModel().setRoot(node);
super.getSelectionModel().
setSelectionPath(new TreePath(node.getPath()));
super.expandPath(new TreePath(node.getPath()));
}catch(Exception ex){
ex.printStackTrace();
I was originally building the root node, then setting it as the root, then adding additional nodes to the root in the call to renderTree(). So the fix was to build the complete tree structure and then call setRoot(). Otherwise the tree doesn't automatically paint the nodes when they're added via node.add(nodeChild).
It was just a coincidence that I discovered this problem with nodes having the same name.
Thanks for all your great input!
