--------------------------------------------------------------
Hello. I have a workflow that contains a business rule as the last task, and exists on the flow just prior to a terminal (stop) task (jBPM 5.4.0). When this business rule task is present on the workflow definition, the afterProcessCompleted() event never fires on the DefaultProcessEventListener that I am attaching to my knowledge session. If I remove the business rule task in designer and re-execute the workflow, the event does fire on the DefaultProcessEventListener.

I do not have any special configuration anywhere else in my setup that relates to this business rule task, as I was given this workflow by a third party. The code for the business rule from designer is as follows:

<bpmn2:businessRuleTask xmlns:bpmn2=" http://www.omg.org/spec/BPMN/20100524/MODEL http://www.omg.org/spec/BPMN/20100524/MODEL" id="_51E71516-F613-4F75-BC82-88975FD75864" drools:selectable="true" xmlns:drools=" http://www.jboss.org/drools http://www.jboss.org/drools" drools:ruleFlowGroup="Retract" name="Retract_Object">
      <bpmn2:incoming>_ABC4091E-50C7-4B41-88D9-C4592DF259E3</bpmn2:incoming>
      <bpmn2:outgoing>_D86BD4F5-5151-4D67-863B-5AAE9D56E08E</bpmn2:outgoing>
</bpmn2:businessRuleTask>

The workflow basically goes like this:

start => human task => script task => business rule task => stop    [afterProcessCompleted() does not fire]

start => human task => script task => stop     [afterProcessCompleted() fires as expected]

I am new to jBPM and drools, and I was wondering if anybody can explain this behavior, and how to get the afterProcessCompleted() event to fire? Thanks in advance for any insight.

Sorry it took so long to get back, as I was running some tests on this issue. I was able to solve my problem by doing the following in my process event listener:

public void afterNodeTriggered(ProcessNodeTriggeredEvent event) {
     ksession.fireAllRules();
    }

This advances the process when a business rule task is encountered. This post pointed me in the right direction towards calling fireAllRules():

And thanks for replying Demian
