Hi all, I've looked in JESS in Action: not, test and exists, and isn't firing a rule that should advise user that an object was not found. In the following code ?x is the element I'm looking for. What should I do?
(defrule object_not_found (not (exists (object (is-a vine)(name ?x)))) => (printout t "Not found!!!!!.") ) PS.: Thanks for your previous help! Thanks in advance Roberval --- Acabe com aquelas janelinhas que pulam na sua tela.
