A sub-process can generate different BPMN Error (throw end events, connectors with a policy 'throws a BPMN Event').
On my Call Activity, I place a boundary event, without any "associate error", plus a transition to "manageSubError tasks"
When I execute my process, if an error is thrown from the sub-process (and whatever the error), then the boundary catch the error and goes to the "manageSubError" tasks.
Is that the expected behavior or a Side effect?
Can I have sure that I will have the same behavior in 7.11, 7.12, etc. ?
