I’d like to set the initial expanded state in = my tree such that only the top-level root node is expanded. In my case, = there is only one root node and it may have one or more child = nodes.

I thought the following would do it, but the second = call to getKeySet() on the PathSet object returns = null:

// Collapse all nodes

CoreTree tree =3D = getTree();

tree.getTreeState().getKeySet().clear();

// Add the first (top-level) node to the current path =

ArrayList<String> path =3D new ArrayList<String>();

path.add(new = String("0"));

tree.getTreeState().getKeySet().add(path);<= /span>

What is wrong with this = technique?

Thanks in advance,
