Not sure exactly what you mean with the "etc". in "no global flags etc" but you could use a declared control fact, for example:

declare CF
    ruleName : String
end

rule "A1"
    salience 100
    when
        xxx1
        not CF( ruleName == "A1" )
    then
        yyy1
        CF cf = new CF();
        cf.setRuleName("A2");
        insert(cf);
end

rule "A2"
    salience 90
    when
        xxx2
        not CF( ruleName == "A2" )
    then
        yyy2
        CF cf = new CF();
        cf.setRuleName("A1");
        insert(cf);
end

Hi,

I have a group of rules with salience which I would like that only the first activated rule will fire.

I cant use the activation-group attribute because each rule can fire number of times, and i want only this rule to be fired in that group:

rule "A1"

salience 100

ruleflow-group "A"

activation-group "A"

when

   xxx1

then

   yyy1

end

rule "A2"

salience 90

ruleflow-group "A"

activation-group "A"

when

   xxx2

then

   yyy2

end

If Rule A1 run (activated number of times), rule A2 should not run.

Is there a way to do that? (no global flags etc.)

Thanks

Yaniv
