Error Listener ?

[thomasl]

Hello,

I have a system in which BPM scripts may be added by external users and are likely to throw technical exceptions (invalid scriptTask for instance). I understood that if RuntimeService.startProcessInstanceById (for instance) fails and throws an exception, the Activiti transaction is rolled back and no process instance exists in the database.
In such a case, the message in the thrown ActivitiException is sometimes not detailed enough to provide debugging information and I am looking for a hook to be able to retrieve information form the Activiti Engine after the process failed (exception in ScriptTaskActivityBehavior for instance) but before the transaction is rolled back. I have tried adding an ExecutionListener on the process but found out that it works only when the process succeeded. Is there any kind of error listener mechanism in which I may be able to run process queries such as retrieving executed activities list or process variables when an exception occurs ?

Thanks,

Tom

Can you catch exception and fire some kind of event?

Hi Martin,

Thanks for your reply. You mean the exception in the scriptTask or other activity ? Unfortunately not, since scripts are written by external partners. In addition, we may have exception elsewhere, for instance if a conditionExpression contains an unknown variable, a org.activiti.engine.impl.javax.el.PropertyNotFoundException is raised and the whole script fails.
In such a case, I would like to be able to retrieve a few process variables and the list of executed activities so that I am able, for instance, to find out how far the Activiti script went and rollback external non-transactional resources.

Thanks,

Thomas
