Hi
Newbie to BPM/BRMS. I am trying to run a rule after a script task in jBPM 5.3. I am trying to do everything through the jbpm web console, except for the flow group designing, since there is no provision, to my knowledge to design the rule flow in jBPM console. I tried calling fireAllRules() through ksession in the script. I also tried to call fireAllRules() through listener as suggested in another thread here. Never the less I am unable to do it. I must be doing some fundamental mistake here, can anyone suggest me.
Here are the sources:
