[rules-users] DAO call in LHS

though I referred other thread about this topic, I'm not successful to make a dao call. I beg your pardon to ask again. 1. I want to pass the fact object to the dao function which returns boolean. I tried following rule and getting " Unexpected token '$fact'" as eclipse compilation error. Please guide with right syntax. global RuleDAO dao; rule "test DAO call" $fact : Fact(some condition) fact : Fact(dao.isValid($fact)) then #do something end 2. Will be there any performance issue for above kind of rule?
