Hi Drools Rulers, I am new to drools and I’ve configured a rule with the following: ------------------------------------------------------------------------ rule "my rules"     ruleflow-group "nike"     no-loop true     when         $nikeShoe : NikeShoe() from shoeManager.getNikeShoe(xxxx) then    xxxx end ------------------------------------------------------------------------ When I run rule group “Adidas”, the getNikeShoe() query in group “nike” is executed. Although I did NOT invoke the rule group “nike” when executing rules, the shoeManager. getNikeShoe () call is always executed. Seems somehow the condition is pre-checked by drools somehow. Anyone could please share what I did wrong? I definitely don’t want to invoke group “nike” when executing group “Adidas”. Thanks in advance!

Is that true (i.e. all rules evaluated even though they won't be fired) also of agenda groups? -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Action-tp3604296p3604571.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Just to add to what salaboy wrote, *all* LHS are evaluated as Facts are inserted. If I am not mistaken, ruleflow-group (like agenda-group) only controls what activations (RHS) on the agenda caused by the evaluation of the LHS are executed.

So if we have, for example, a set of rules that we know only need to be evaluated under certain conditions or for discrete types of Facts, would it be more efficient to put them in a separate knowledge sessions? Meaning, instead of one session where we insert all objects and then fire agenda-group-1 and then agenda-group-2, we have knowledgeSession1 and knowledgeSession2, insert only the facts relevant to each session, and fire all rules on each session. -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Action-tp3604296p3604632.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
