Sporadic Issue in BPMN Workflow
Maria Prabudass
Hi,
We are experiencing an intermittent issue in our BPMN workflow using jBPM 5.4.0.Final, where the next node is not consistently created after completing a task.
Key observations:
- The task is completed successfully, but the next node is sometimes not triggered.
- This issue occurs sporadically; it works correctly most of the time but fails under certain conditions.
- The problem is specific to a particular user task in the BPMN process.
- No errors or exceptions are raised when completing the task.
- The issue arises more frequently when tasks are rapidly created and completed within the same process instance.
We suspect the problem may lie in the following method. It appears that the flow does not enter the if block because the work item ID is holding the previous work-item ID of the process instance, causing the if block to be skipped and preventing the next node from being created:
Code:
org.jbpm.workflow.instance.node.WorkItemNodeInstance
public void workItemCompleted(WorkItem workItem) {
if ( workItemId == workItem.getId()
|| ( workItemId == -1 && getWorkItem().getId() == workItem.getId()) ) {
removeEventListeners();
triggerCompleted(workItem);
}
}
How can we resolve this issue?
Regards,
Maria
