Re: [rules-users] RuleFlow and facts

First of all, why are you doing this: p : Parametre( para1 : para1) eval (para1 == "para1") You can directly do: p : Parametre( para1 : para1 == "para1") Can you show us the Drools Flow file? To see what nodes do you include in that? Probably your Ruleset node (ruleflow-group) is never reached.
