[rules-users] How to make a "Loop-Ruleflow"????

Hi everybody. I am trying to make a ruleflow that, once processed, causes the rule engine to infinitely loop. I have got a *User* Object in my object model. It has got a *getLogin()* and *setLogin(*) methods. The login field stands for the "User name", so it is a String. First I insert an Object in the WM, with login==A. Then I generate the following rule-flow-groups: *rule "rule_ab" * * ruleflow-group "ab" * * when * * u:User( login == "A" ) * * then * * u.setLogin("B"); * * System.out.println("a - > b"); * * update(u); * *end * ** *rule "rule_ba" * * ruleflow-group "ba" * * when * * u:User( login == "B" ) * * then * * u.setLogin("A"); * * System.out.println("b - > a"); * * update(u); * *end * I'd like to define a ruleflow that gives me in output something like this: a - > b b - > a a - > b b - > a a - > b b - > a a - > b b - > a a - > b b - > a a - > b b - > a .... looping... How can I do it? In other words I want those rules to be executed in parallel and I want to define this "parallelism" using the ruleflow graph, Is It Possible??? Thank You Again! Massi. P.S. Ah.... I solved that matter with the rule.package...
