Hello,

I want to modelize a bpmn process with a multi-instance sub-process.  
The instances of that sub-process are executed sequentially.  
I add a event Sub-Process at the sub-process level.  
This event sub-process send a notification related to BPMN error recieved.

If a BPMN error is thrown by a service task within my sub-process, event sub-process is triggered, but all next instances are affected. My process ended.

How can I implement a BPMN solution to prevent multi-instance break ?

Thanks

Vincent
