BpmnError not caught in boundary

larxxor — Tue, 08 Mar 2016 13:14:51 GMT

I'm doing som investigations in Activiti 6 beta2.Created a flow, with different type of tasks, listeners etc. Wanting to test boundary error catching, I put a ServiceTask in a subprocess. The ServiceTask calls a java delegate, which throws a BpmnError in the execute method :LOGGER.info("throw BpmnEr

Hi Larxxor,

jUnit test would help.

I am exploring this further, and it seems that listeners is sometimes not called, for some reason.

I have a case where a TaskListener works nicely in one process, but is never called in another. In designer, those two UserTask look completely identical.
I will investigate and work on a junit test.

Well, I have identified the issue. It has to do with subprocesses.

I have attached a simple bpm : "junit2.bpmn"
It has no subprocesses, a single UserTask with a listener. It works as expected.

I have attached a another bpm : "junit.bpmn"
It has a UserTask within a subprocess, with the same listener. It never calls the listener.

The same happens for boundary events on subprocess, which was my original issue.

I created JUnit test for it : It is a regression in Beta2 !

Created two junit tests, one with, one without listener inside subprocess.

It works in Beta1, fails in Beta2. You want me to create Jira issue with the junit tests, I assume?

Hi,

could attach the whole project with java jUnit test class?

Ahem, I uploaded the complete project to ACT-4133. Do you mean attach to forum?

Hi Larxxor,

Sorry my fault - I did not check jira issue.
The problem is already solved in the master head revision. The problem was that process bpmn did not search for tasks inside subprocesses.


      FlowElement flowElement = process.getFlowElement(taskEntity.getTaskDefinitionKey());

was changed to


      FlowElement flowElement = process.getFlowElement(taskEntity.getTaskDefinitionKey(), true);

in org.activiti.engine.impl.persistence.entity.TaskEntityManagerImpl#fireTaskListenerEvent
