Incoming sequenceflow for intermediateCatchEvent

BPMN & Modeling Discussion & Questions
1

Hi community,

I want to ask about the camunda BPMN rule:
An intermediateCatchEvent connected to an event-based Gateway must have a single incoming sequence flow.
I would understand an outgoing case but why incoming?

I have mistakenly violated the rule with the below bpmn.

I am pretty sure it is defined by the BPMN specification that way. Don’t ask me why, though :slight_smile:

Cheers,

Hi @Michal_S,

An intermediate catch event after an event-based gateway just can have one sequence flow because the intermediate catch event belongs to the configuration of the gateway. Means that it doesn’t work technicly like a normal intermediate catch event. You couldn’t deploy the model in an Engine.

thank you both for the answer.
You have explained me that the rule is not based on some proprietary Camunda decision
