I have a simple ruleflow (jbpm flow) with two nodes, after the rules fire in the first node, it simply will not move to the next node, I think the below describes the problem, but I still do not understand it **** It appears that the txm.commit() statement in SingleSessionCommandService.execute() method which is invoked for startProcess command somehow leads to removeEventListener(String type, EvenListener listener) which results in the removal of the RuleSetNodeInstance callback of first rule group, therefore, workflow exits at first rule group when fireAllRules is called. -- View this message in context: http://drools.46999.n3.nabble.com/Simple-Ruleflow-exits-after-first-set-o...
