Executable checkbox disables after deleting diagram with pool

[Camundaan]

Describe the Bug
After deleting the last pool with a working diagram in the WebModeler, the "executable" checkbox is automatically disabled and stays disabled even after creating an error-free diagram after that.

Steps to Reproduce
Recording
Passcode: c@4R?Sp*

1. Create a working diagram in a pool
2. Delete pool
3. Checkbox "executable" is disabled and stays disabled even when users create a new working, error-free diagram.

Expected Behavior
Users would expect the executable checkbox to be automatically enabled again when creating a new diagram, with or without a pool.

Environment
WebModeler

• OS: [e.g. MacOS 10.2, Windows 10]
• Modeler version: [e.g. 2.0.0]

I can reproduce this also on latest modeler release.

Root Cause

When the last participant is deleted, bpmn-js replaces the collaboration with an empty process without any execution semantics.

This might be a case to be fixed in https://github.com/camunda/camunda-bpmn-js-behaviors to keep the config of the last Process

@marstamm can I add this to ready, so we can discuss this in the next planning?

@christian-konrad, I moved it to ready. You can move any issue to ready that you want to discuss in the next planning meeting. no need to check in first :)
