Unknown type <bpmn:MultipleEventDefinition>

As far as I understand you want to be able to create events with multiple event definitions through the palette, the context pad and the replace menu. bpmn-js can already render all BPMN 2.0 elements so adding support for multiple events is a matter of adding the ability to create them. Note that there is no existing solution for maintaining multiple event definitions. bpmn-js-properties-panel only supports single event definitions.

There’s a general example of customizing all of these: https://github.com/bpmn-io/bpmn-js-examples/tree/master/custom-elements#customize-editor-controls

I’ve created a more specific example that let’s you append end events with multiple event definitions through the context pad:

28-01-_2021_14-23-41

The crucial part is:

function createMultipleEndEvent() {
  const endEvent = bpmnFactory.create("bpmn:EndEvent");

  const errorEventDefinition1 = bpmnFactory.create(
    "bpmn:ErrorEventDefinition"
  );

  const errorEventDefinition2 = bpmnFactory.create(
    "bpmn:ErrorEventDefinition"
  );

  endEvent.set("bpmn:eventDefinitions", [
    errorEventDefinition1,
    errorEventDefinition2
  ]);

  errorEventDefinition1.$parent = endEvent;
  errorEventDefinition2.$parent = endEvent;

  const shape = elementFactory.createShape({
    type: "bpmn:EndEvent",
    businessObject: endEvent
  });

  return shape;
}
