Hi, I have a problem with ruleflow. I have a RF like this : Start ---> log : < init > ---> ruleflowgroup : INI ---> log : < next Step > ---> ruleflowgroup : AKT ---> END And a rule like this. when then drools.getWorkingMemory().startProcess("My Flow"); But when i start a stateless Session, i have this result : 1 : log init 2 : rules in ruleflow-group INIT are activated. 3..... nothing else Log < next Step > and ruleflow-goup AKT are not launched. Could you help me ? I use Drools 5.1.1 and guvnor 5.1.1. thanks. Gaetan
