Testing JTree setSelectionPath(TreePath path)?

    How can I tell if a call to JTree setSelectionPath(TreePath path) fails
    because of an invalid path? I have a search function set up which
    stores TreePaths. While browsing the TreePaths I choose one or more
    and when I do, I expand the chosen TreePath (using setSelectionPath())
    and select the TreeNode. This works great. Now, if the structure of
    the tree changes, I want to be able to know that my attempt at
    setSelectionPath() didn't work. I thought that perhaps getting the
    selected object after calling setSelectionPath() and testing for null
    would work, but instead it returns what seems to be the object at the
    bottom of the TreePath I attempted to use to set the selection in the
    first place.

    Any ideas? Is there a path validation function I'm overlooking?

    Thanks,
