Thanks for your comment. In the end I did leave error throw-catch in the training. The technical folks seem to prefer it, and some use it to distinguish technical from business exceptions. I’m not a fan of conditional events, because they imply “some magic happens”. It says that the process engine is aware of conditions and can respond to changes immediately, and that is described nowhere in the spec. In every other case, in responding to a condition BPMN assumes the process receives a message, signal, or other explicit trigger, or an activity detects the change. So I agree conditional events are useful hand-waving, but seriously… Do you know of any BPMN engines that are condition-aware?
