SetRootVisible - not as advertised

Question

Hi Everyone,
I can't get JTree.setRootVisible to work.
I've subclassed JTree and call setRootVisible in the constructor. Then I add the nodes. If I call it passing true, all the nodes I add are collapsed but visible (which is fine). If I call it passing false, no nodes appear, even if I try and explicitly expand them with code such as :
      for (int i = 0; i < getRowCount(); i++)
         expandRow(i);
      }After I add the nodes, I've tried various combinations of setRootVisible(true/false) and even calls to repaint but nothing works.
I'm also using custom cell editors, but like I said, they work fine if I call setRootVisible(true).

Try expanding the root with:
tree.expandPath(new TreePath(root));
