Hi - I want to have a Signal End Event that signals other processes - and sets their business key.
According to https://github.com/camunda/camunda-docs-manual/blob/master/content/reference/bpmn20/events/signal-events.md#passing-a-business-key I should be able to set the businessKey
on the signal with:
<camunda:in businessKey="${execution.processBusinessKey}" />
However I can’t see any way to do this in Camunda Modeler - am I missing something? If I set the value in the bpmn file, nothing is visible in the Modeler.
