What is the special feature of events with the event definition None, Conditional event, Multiple event, and Parallel multiple event?

Start events

In superior processes, process instances are created at start events with the event definition None in line with the attribute Frequency or the assigned schedules.

In subprocesses, start events with the event definition None and activities and gateways without incoming sequence flow are triggered, when a process folder reaches the subprocess.

Start events with the event definition Conditional or Multiple behave like start events with the event definition None.

Intermediate events

If an intermediate event with the event definition None is activated, a process folder is immediately routed through each outgoing sequence flow.

Intermediate events with the event definition Conditional, Parallel or Multiple behave like intermediate events with the event definition None.

End events

If an end event with the event definition None is activated and no other process folder is active, the instance is completed. In a subprocess, an end event with the event definition None marks the end of the subprocess.

End events with the event definition Multiple behave like end events with the event definition None.
