Hello flowable-team,

as suggested [here](https://forum.flowable.org/t/received-message-before-messageeventsubcription-was-added/3301), we try to develop an Send-and-Receive-Task by implementing _TriggerableActivityBehavior_.

Dependent on the received answer, we tried to bind an _BoundaryErrorEvent_ to the Triggerable activity.

While throwing a _new BpmnError(“foo”)_ in the _.execute_-method works as expected, throwing the error inside the _.trigger_-part won’t catch the error in the boundary error event.

I found a pretty old [thread](https://community.alfresco.com/thread/224478-throwing-an-exception-from-a-signal-method#comment-30075) dealing with the same problem - but I couldn’t find out if this problem was solved or if the workaround is still appropriate.

Are there any news regarding this topic?

Thank you for your efforts!

I don’t believe it works in the trigger() method, that would be a new feature that needs to be added.

Hello,  
I have the same issue here. The Boundary Error Event is ignored when throwing a BpmnError from TriggerableActivityBehavior#trigger(…) :’(

I use version 6.4.2 of flowable. Is there any plan to fix this?

Thanks
