Re: [rules-users] Constraints over Lists

Hi Thank you for the reply. That actually did not help. However, I found another way of writing the rule involving a method. It is as follows: rule "listEq1" when P : Project() eval( isDefined(P.list1) && neqq(P.getList1(), new ArrayList(Arrays.asList( new Object[] {1, 2, 3} )))) then System.out.println("Lists are not equal - 1"); end Kind of strange, but works. -- View this message in context: http://drools.46999.n3.nabble.com/Constraints-over-Lists-tp4021715p402175...
