Data Store Reference association is removed when changing type of subprocess

[jarekdanielak]

Describe the bug

When I change the type of a subprocess, the associations between tasks inside of a subprocess and Data Store References are gone.

It doesn't happen to Data Store References inside of the subprocess or linked to the subprocess itself.

Screen.Recording.2025-02-27.at.12.00.56.mov

Steps to reproduce

1. Create an expanded subprocess with a task.
2. Add Data Store Reference to the task, put it outside of the subprocess.
3. Change the type of the subprocess.
4. The association between the task and the Data Store Reference is gone.

Expected behavior

The association stays.

Environment

• OS: macOS
• Camunda Modeler Version: 5.32

Additional context

No response

As we established, this is not a regression, but simply bad UX.

This needs to be fixed in bpmn-io/bpmn-js

During my testing I noticed that if you reopen a bpmn and try to change the type it behaves as expected. I guess the next step could be to write a test to dynamicly generate a broken bpmn and continue from there

@Buckwich can you attach a link to the branch with a test case?
