Hello, I try to understand how to use Drolls. It's not the first time i work with rules (i know JRules). I have a probleme when i execute my ruleflow. I have some rules which belong to different ruleflow-group. I have put my ruleflow-group in my ruleflow. THe probleme is that my ruleflow never execute the "then" part of my rules. If i delete le ruleflow-group of my rules and i execute the drl file, all my "then" part are executed. I think i have a problem to give my facts to the ruleflow... Is somebody can help me ? thx!!

i have replace my when condition by : p : Parametre( para1 : para1 == "para1"). Thx ! The node is reached, i have an action node after it and il works... http://old.nabble.com/file/p26528902/ruleFlow1.rf ruleFlow1.rf Thx for your help.
