I'm afraid I can't publish as it is, but I hope this would give you a hint:
myrules.drl:
rule "New case"
when
$case : Case(processed==false) from entry-point "case stream"
then
modify ($case){
setProcessed(true)
}
[.... processing code omitted ... ]
insert(kcontext.getKnowledgeRuntime().startProcess("com.mycompany.Process",
parameters));
end
rule "job complete"
ruleflow-group "jobs group"
when
$processInstance: WorkflowProcessInstance()
then
Job job = (Job)$processInstance.getVariable("var");
update(job);
end
process.bpmn:
<?xml version="1.0" encoding="UTF-8"?>
<definitions ....>
<process processType="Private" isExecutable="true"
id="com.mycompany.Process" name="process" >
[one start node and lots of nodes here, one that ends in the next ]
<businessRuleTask g:ruleFlowGroup="jobs group" id="job complete"
name="complete job"/>
[ lots of nodes after, ending in an end node]
</process>
</definitions>
As you can see the rule "New case" is not in any group and is responsible (
if it is the case ) of launching the process, and then that process invokes
the bussinessrule group "jobs group". As stated, what we see is that the
rule "job complete" never gets fired.
