Re: [rules-users] multiple rules modifying the same fact

Hi, Generally, there are 2 common approaches. Pick your choice depending on your case. 1) Do not modify the working memory. Rules will not be retriggered and an infinite loop is avoided. This is only feasible if your rules do not have to react on changes made by other rules. I.e. the state that your objects are in when calling the engine, can be considered final. 2) Insert (or modify) control objects to make sure that rules do not fire over and over again. I.e. in your RHS, you "mark" that the rule has already fired. F.e. insert(new RuleOneJustFired() ); In your LHS, you check for the presence of these markers in your working memory. A third option would be that you fix the sequence of your rules by using something like ruleflow-groups.
