[rules-users] timer and duration

Hello there. I seem to have trouble with the "timer" operator which is documented to have superseded the "duration" operator for use in the rule body. I might have something to do with the "not" operator I use in my rule. Scenario: A is a fact, B is an event When I write something like this rule "test" timer(int: 5s 5s) when $a : A() not (exists B(a == $a)) then insert(new B($a)); // which means in the new B object: B.a = $a end I expect this rule to fire every 5 seconds if and only if the LHS is true. I just insert a few A objects at the beginning. So I expect this rule to fire ONCE, because it will insert the B event which makes this rule's LHS evaluate to false in the future. BUT, reality is, this rule fires every 5 seconds, no matter what. Using the deprecated duration operator with "duration(5s)" instead of the timer operator, it works as expected. I assume, that timer works differently compared to duration. So I conclude that duration should coexist. Or am I missing something here on the usage of the timer operator? Thanks in advance.
