Write your constraints so that only one rule fires, e.g., by testing
price == null.
Ideally, you should also avoid salience by fully describing the cases
for prices 1 and 2.
Using flow control and salience - this isn't rule based programming
any more, just a very elaborate way of implementing sequential logic.

Re: [rules-users] Lock-on-active and ruleflow-group
Do you activate the ruleflow-group before you insert the Car fact?
No, I don't think so.
This is body of my test class:
public class CarKnowledgeBaseTest {
@Test
public void shouldObtainPriceWhereSalienceIsBigger() throws Exception {
//given
KnowledgeBase kbase = readKnowledgeBaseFromDrl();
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
//when
Car car = new Car(red, small);
Car car2 = new Car(red, big);
ksession.insert(car);
ksession.insert(car2);
ksession.addEventListener(new DebugAgendaEventListener());
ksession.startProcess(com.car.test);
ksession.fireAllRules();
ksession.dispose();
//then
assertEquals(Integer.valueOf(2), car.getPrice());
assertEquals(Integer.valueOf(1), car2.getPrice());
}
private KnowledgeBase readKnowledgeBaseFromDrl() {
KnowledgeBuilder knowledgeBuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
knowledgeBuilder.add(ResourceFactory.newClassPathResource(com/car/test/car.drl),
ResourceType.DRL);
knowledgeBuilder.add(ResourceFactory.newClassPathResource(com/car/test/flow.rf),
ResourceType.DRF);
if (knowledgeBuilder.hasErrors()) {
throw new
RuntimeException(knowledgeBuilder.getErrors().toString());
}
KnowledgeBase knowledgeBase =
KnowledgeBaseFactory.newKnowledgeBase();
knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());
return knowledgeBase;
}
}

Re: [rules-users] Lock-on-active and ruleflow-group
But when I use activation-group only one fact has price. I would like to
insert two facts (or more) and only one rule invoke per fact.Like in my test
class.
Could you look at use case that I attached in my first post? Thanks.

[rules-users] Lock-on-active and ruleflow-group
I have three rules: rule First rule salience 20 ruleflow-group rfs_1 lock-on-active true when $c: Car(color == red) then $c.setPrice(1); update($c); end rule Second rule salience 25 ruleflow-group rfs_1 lock-on-active true when $c: Car(size == small) then $c.setPrice(2); update($c); end rule Second step salience 40 ruleflow-group rfs_2 lock-on-active true when $c: Car() then System.out.println($c); end I have class, for example Car, which has three prioperties: color, size, price. I insert into session fact-Car(red, small), next start process, and execute rules. After that, price value is 1. I thought that Second rule should be fired only because it has bigger salience but it is exactly the opposite. Could anyone explain me why first rule was executed/fired and what can I do to fire only Second rule (without invoking First rule).
