Multiple Diagrams per BPMN file

[falko]

The upcoming demo of the OMG's BPMN Model Interchange Working Group (MIWG) will showcase BPMN files containing multiple diagrams. Is there a chance to support this in the modeler?

Here is the current example file:
Multi-diagram.bpmn.zip

It contains the following three diagrams:

Only the 'IT' diagram shows up in Camunda Modeler. There are no XML errors reported in the log.

How should we support multiple diagrams? Is switching between the diagrams a suitable way to go?

[falko]

Yes, totally. Other vendors show them on multiple tabs at the bottom, just like we already show the switch between diagram and XML.

A BPMN file with multiple diagrams has become an official test case of the BPMN MWIG Test Suite:

This needs to be addressed via bpmn-io/bpmn-js#87.

Infrastructure provided upstream. We need to decide if we'd like to support this in the modeler visually, too.

There is a plugin which implements this feature request: https://github.com/sharedchains/camunda-modeler-plugin-multidiagram/
