Re: [rules-users] activation-group issue

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
