[rules-users] [drools 4] firing a partial set of rules and consequences

Can I fire a partial set of rules? Say I have 3 rules: fastRuleA, fastRuleB, slowRuleC. What's the best way to only fire the group of fastRule1 and fastRule2? AgendaFilter looks like a good way of doing this, but: If between 2 rule fires, I change a fact, but change it back to it's original state, will the rule be not refire, just like if I hadn't changed it temporary? for example fact1 is used in slowRuleC: fireAllRules(); // fires slowRuleC fact1.a++; fact1.a--; fireAllRules(); // does not fire slowRuleC? Does still apply if I fire other rules meanwhile? fireAllRules(); // fires slowRuleC fact1.a++; fireAllRules(notSlowRuleCAgendaFilter); // slowRuleC is ignored // if I did not filter it out it would have fired of course fact1.a--; fireAllRules(); // does not fire slowRuleC? or does it? // a hasn't is the same since the last time slowRuleC was fired -- With kind regards, Geoffrey De Smet
