Jtree expand all not working

Question

I have a very large jtree, that at it second level gets loaded from a JDOm file.
The problem is I am having a problem expanding all the nodes under a
particular node. I need an expandAll method. Nothing I have tried has
expanded beyond the child level.
After a few permutations my code right now is
public void expandAll(DefaultMutableTreeNode node)
Enumeration list = node.breadthFirstenumeraion();
while (list.hasMoreElements())
TreePath treePath = new
TreePath(((DefaultMutableTreeNode)list.nextElement()).getPath()))
tree_m.expandPath(treePath);
Am i missing something about expandPath?
I even use the code from JTree example to the reload the model.
But it still only shows the nodes children, not the children's children....etc.

Hi!
You can try these methods where treeRoot is the root node of the tree:
* Collapses the function group tree.
public void collapseAll() {
for (int i = treeRoot.getChildCount(); i > 0; i--) {
tree.collapseRow(i);
* Collapses the function group tree.
public void expandAll() {
for (int i = treeRoot.getChildCount(); i > 0; i--) {
tree.expandRow(i);
