Do something when max retries is reached for a task

spartan

I would like to move the execution point to another branch of the workflow when the max number of automatic retries is reached for a service task.

I guess I have to add an "errorBoundaryEvent" to the monitored service task and that I could handle the routing from the delegate ; if {max retry is reached } then {move to error handling branch} else {let the retry engine do his part}. But I don't like the idea of handling it that way plus I dont want to duplicate that routing code for every single service task we have. I'd rather have it handled on the engine side. Do you know what would be a proper solution ?

So I ended up implementing that logic in the delegate. I'm throwing a BpmnError when max repeat is reached. The errror handling branch is then started (by a errorBoundaryEvent).

The problem is that now it ends up with a "RollbackException: Transaction marked as rollbackOnly"…

Hi Spartan,

There are many possibilities e.g.:
- try to implement your custom org.activiti.engine.impl.jobexecutor.FailedJobCommandFactory. Add it to the process engine configuration. In the created command when retries are 0 -> throw BpmnError.
- Listen to JOB_RETRIES_DECREMENTED entity event and when there is 0 -> throw BpmnError event.

Just tried that : The BpmnError is thrown but my error handling branch is not triggered…

Hi,

Can you create jUnit test for your case?
