[rules-users] activation-group issue

[Tihomir Surdilovic]

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
