RE: [rules-users] many response

You need to remember that a rule runs every time the patterns are matched. For example:- rule "example" when $a : ObjectA() $b : ObjectB() then System.out.println("Rule 'example' ran"); end Working Memory:- 1 - ObjectA 2 - ObjectA 3 - ObjectB 4 - ObjectB The rule will run four times; once for each combination of ObjectA and ObjectB (1, 3) (1, 4) (2, 3) and (2, 4). Object models are flattened in Working Memory so if you need to impose a relationship you need to add this to the rule. For example:- [one-to-one mapping] ObjectA has one child ObjectB. Method suggestion (returns an instance of ObjectB): ObjectA.getObjectB(); rule "example" when $b : ObjectB() $a : ObjectA(objectB == $b) then System.out.println("Rule 'example' ran"); end [one-to-many mapping] ObjectA has many child ObjectB. Method suggestion (returns a List): ObjectA.getObjectBs(); rule "example" when $b : ObjectB() $a : ObjectA(objectBs contains $b) then System.out.println("Rule 'example' ran"); end Check that this is not the cause of your multiple unexpected executions.

Example: rule "userrole" when user1: BnUserValue(nameuser : name) and Role : BnRoleValue() and ActiviteOut : BnNodeValue(bnRole == Role,executor == nameuser ) and ActiviteIn : BnNodeValue(bnRole == Role ) and lien: BnEdgeValue(outBnNode == ActiviteOut,inBnNode ==ActiviteIn ) then System.out.println("cette personne "+user1.getName()+ " ne peut pas executer cette activiter"); end the execution result cette personne ismail ne peut pas executer cette activiter cette personne ismail ne peut pas executer cette activiter cette personne ismail ne peut pas executer cette activiter cette personne ismail ne peut pas executer cette activiter cette personne ismail ne peut pas executer cette activiter cette personne ismail ne peut pas executer cette activiter so the result is repeat 6 I don't know why? thank for your help Ismail ________________________________ Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
