Note: this does get called, but in a tricky way.  If externally, someone calls
setCategoryPath, nothing happens because it is overridden in this class to do nothing.
However, if updatePath is called, then this method calls super.setCategoryPath which
bypasses the overriddenness of setCategoryPath, resulting in this method getting called.
