Mohammad, Depending on how your list widget logic is implemented, as I understand it, if you try and return the value in an index, empty or non existing will produce nothing in the output of your filter (if it is the only value to be returned), if a value is returned the list body or list template will be used, so there's no need for a test for blank.
