5:37 p.m.
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").
Thanks

"Whenever a ruleflow-group becomes active [...], any rule within that group
that has lock-on-active set to true *will not be activated any more*."
(Emphasis added by me.)
Do you activate the ruleflow-group before you insert the Car fact?

"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"),

knowledgeBuilder.add(ResourceFactory.newClassPathResource("com/car/test/flow.rf"),

throw new

}

knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());
return knowledgeBase;

You should use activation-group "price" or similar, not lock-on-active.

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.

Modules (=agenda-group and ruleflow-group) are fine for large-scale
rule flow control. First choice for fine-grained rule execution
control is - Logic.
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.

Modules (=agenda-group and ruleflow-group) are fine for large-scale
rule flow control. First choice for fine-grained rule execution
control is - Logic.
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.
