     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.
