I'm using Activiti 5.21.0 as BPM engine. Asked to keep everything simple, i removed gateways(I know it is not good). Now the workflow is simpler. like[img]https://camo.githubusercontent.com/458b61e9114bec5ee84e33d827e8f6f031f60e2a/687474703a2f2f7777772e63...[/img]I set conditionExpression for every sequenceFlow, looking forward only one of userTask 2&3 would be activated depend on the exclusive condition set on the flows. It works fine only when userTask1 is not ParallelMultiInstanceTask. But if i set userTask1 parallel, when complete userTask1, no condition is calculated. userTask2 and userTask3 are both activated.After looked through codes, i found that ParallelMultiInstanceBehavior.leave() act differently against other Behaviors.
if (joinedExecutions.size() >= nrOfInstances || completionConditionSatisfied(execution)) {
// Removing all active child executions (ie because completionCondition is true)
List<ExecutionEntity> executionsToRemove = new ArrayList<ExecutionEntity>();
for (ActivityExecution childExecution : executionEntity.getParent().getExecutions()) {
if (childExecution.isActive()) {
executionsToRemove.add((ExecutionEntity) childExecution);
}
}
for (ExecutionEntity executionToRemove : executionsToRemove) {
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("Execution {} still active, but multi-instance is completed. Removing this execution.", executionToRemove);
}
executionToRemove.inactivate();
executionToRemove.deleteCascade("multi-instance completed");
}
executionEntity.takeAll(executionEntity.getActivity().getOutgoingTransitions(), joinedExecutions);
}
I wonder if there are some reason when leaving ParallelMultiInstance, every outgoing should be taken. Is it possible to filter OutgoingTransitions using conditions?Greetings.
