ActivitiEventListener

davanna

Hi Members,

I have implemented ActivitiEventListener and put in my logic for the activiti engine to make the callbacks. I do see that when I delete the process, I do not get callback for eve type PROCESS_CANCELLED but I get call back for ENTITY_DELETED. Has anybody faced the same issue ?

Thanks

Hi,

In the above case, you are not cancelling right ? you seem to be deleting the process.

didn't find any issue, got PROCESS_CANCELLED followed by some others event

I did record all the events that were thrown as a result of call to runtime.deleteProcessInstance(instanceId, deleteReason). I had configured the activitilistener as follows :

<extensionElements>
   <activiti:eventListener class="WorkflowListener" entityType="process-instance" />
</extensionElements>

For the above configuration, following events were thrown:

********************************* ENTITY_DELETED
********************************* ENTITY_DELETED
********************************* ENTITY_DELETED

I changed the configuration as follows:

<extensionElements>
   <activiti:eventListener class="WorkflowListener" />
</extensionElements>

The following events were emitted for the above configuration:
********************************* ACTIVITY_CANCELLED
********************************* ENTITY_DELETED
********************************* HISTORIC_ACTIVITY_INSTANCE_ENDED
********************************* HISTORIC_ACTIVITY_INSTANCE_ENDED
********************************* HISTORIC_ACTIVITY_INSTANCE_ENDED
********************************* HISTORIC_PROCESS_INSTANCE_ENDED
********************************* ENTITY_DELETED
********************************* HISTORIC_PROCESS_INSTANCE_ENDED
********************************* ENTITY_DELETED
********************************* ENTITY_DELETED
********************************* HISTORIC_PROCESS_INSTANCE_ENDED
********************************* ENTITY_DELETED

I do not see anywhere PROCESS_CANCELLED event. The documentation for PROCESS_CANCELLED states as below:

/**
   * A process has been cancelled. Dispatched when process instance is deleted by
   * @see org.activiti.engine.impl.RuntimeServiceImpl#deleteProcessInstance(java.lang.String, java.lang.String), before
   * DB delete.
   */

Am I missing something here.

I didn't define any eventType for my listener.
