Exception Handling with Retry

Hi,I have a BPM process that makes many service calls and also has 2 Human Tasks. I now want to implement an Exception Handling to handle Technical Exceptions (example: backend service is not responding, database is down etc).Just wantwed to check if there is any recommended pattern that I can use

I have found the answer for point1. I can throw BPMError() from my JavaClass that implements JavaDelegate. This will makemy process look bit neater as this means that I will not have transitions coming out from each service task.

Not sure how can I go back to the failed activity from the 'Event Subprocess'.

Hi Sam,

I am not aware of API which moves the execution from event subprocess to the defined activity. In fact it is easy to manage it in the DB (just change column value). The implementation is not so complicated in this case.
