Listen to generic events

Hey guys.

The Event Bus didn't made it into Activiti, now I ask myself: How can I register generically for a certain event, not dependant to a specific instace. For example: "Call this Listener evey time any process instance ends". Or "every time I enter a state"… Use case is to plugin some monitoring and cleanup.

Is there a clean and easy way for this?

Thanks
Bernd

Bernd,

The way I solve this in Alfresco integration is the folowing:

- Add a custom BPMNParseListener, eg:
<br> <!– BPMN Parse listener which adds tasklisteners to all userTasks –>&nbsp; <br>&nbsp; <bean id="activitiParseListener" class="org.alfresco.repo.workflow.activiti.AddTaskListenerParseListener"><br>&nbsp;&nbsp; <property name="createTaskListener" ref="activitiCreateTaskListener" /><br>&nbsp;&nbsp; <property name="completeTaskListener" ref="activitiCompleteTaskListener" /><br>&nbsp; </bean><br><br>&nbsp;&nbsp; … <br><br>&nbsp; <bean id="engine" ….<br>&nbsp;&nbsp;&nbsp;&nbsp; <property name="customPreBPMNParseListeners" ref="activitiParseListener" /><br><br>
- The parse-listener adds taskListener (create and complete) to all UserTasks parsed. In our case, you should use the parseProcess listener call to add event-listener(s) to all processes.

This way, all activiti tasks in alfresco are wired to perform some magic
