Hi PVM, You have to declare the variable in both flows, the parent flow as well as the sub flow. Then you also have to map it to the sub flow node. To do that, in the parent flow click the sub flow node and in the properties map the variable in "Parameter In Mapping". I hope it helps :) -- Vie

Some interesting findings but the main question still remains the same. 1. If you have more than one timer ksession.fireUntilHalt() doesn't work. 2. Only way to get more than one timer working is by calling ksession.fireAllRules(). 3. If you trigger the timers with ksession.fireAllRules() then k
