How to attach boundary error event to a service task

Hi, I have a requirement to attach boundary error event to a service task. This service task is part of the same process in which the error is thrown . I have seen examples in activiti source code where boundary error event is either attached to user task or to a subprocess. Here is my bpmn xml fi

Hi Rgoel,

error boundary event can be attached to another tasks too (e.g. Script tasks, Service task….)

Thanks Martin for replying. I have tried attaching it to first service task in a bpmn process. I am throwing bpmn error in 3rd service task in the same process. But my task handler is not invoked, as activiti does not find any error event listeners in the scope. But when I attach to the third service task which is also throwing the error , it works.

Question is whether this can be solved without creating a subprocess ?

I am not sure what are you asking for.
Examples can be found org.activiti.engine.test.bpmn.event.error.BoundaryErrorEventTest on github

Hi, I am using Activiti version 5.17.0 and I am having a similar issue. I have a custom java class that implements ActivityBehavior (actually extends from AbstractBpmnActivityBehavior) and I am throwing a BpmnError from it but my error boundary event isn't catching it. If I use a JavaDelegate instead of an ActivityBehavior then my error boundary event catches the thrown exception. Are error boundary events unable to catch exceptions thrown from an ActivityBehavior and only JavaDelegates?

Any help would be appreciated.
Mike

Ok figured it out, in my custom ActivityBehavior class I was just throwing a BpmnError out of it. If instead I use the ErrorPropagation.propagateError(bpmnError, execution); then it works.

Thanks,
Mike
