Execution listeners on processes or participants are not shown in Operate UI

[pedesen]

SUPPORT-24288

Describe the bug

Instance listeners can not be inspected in the Operate UI when they are defined on a process root or on a participant.

To Reproduce (case A: execution listener on root process)

Steps to reproduce the behavior:

1. Deploy execution-listener-on-root.bpmn (from example-diagrams.zip)
2. Create a task worker with type foo
3. Create an instance for execution-listener-on-root.bpmn process
4. Navigate to instance details view for this instance

Current behavior

When clicking on the root process in the instance history or deselect any element from the diagram, there is no execution listener tab visible, even though there are execution listeners on the root of the process.

Expected behavior

The execution listener tab should be visible and contain listeners when clicking on the root process in the instance history or deselect any element from the diagram.

To Reproduce (case B: execution listener on participant)

Steps to reproduce the behavior:

1. Deploy execution-listener-on-participant.bpmn example-diagrams.zip)
2. Create a task worker with type foo
3. Create an instance for execution-listener-on-participant.bpmn process
4. Navigate to instance details view for this instance

Current behavior

The participant on the diagram is not clickable, so the execution listener tab is never shown for listeners on the participant.

Expected behavior

Participants should be selectable and show related listeners when selected.

🔍 Root Cause Analysis

💭 Proposed Solution

👉 Handover Dev to QA

• Changed components:
• Side effects on other components:
• Handy resources:
  BPMN/DMN models, plugins, scripts, REST API endpoints + example payload, etc :
• Example projects:

• Commands/Steps needed to test; Versions to validate:

• Docker file / HELM chart : in case that it needed to be tested via docker share the version contain the fixed along with version of other services .

• Release version ( in which version this fixed/feature will be released):

📗 Link to the test case

User can see the Listeners tab in the details view when a listener is added to root process or participant elements

@ArezooAzar To test this you can simply follow the same steps to reproduce and example bpmn processes listed in the description of this issue. The expected behavior is also described there (basically the listeners attached to the process or participant (root flow node on Instance History panel) should be visible.

@vitorwtavares: Where can I find the fix? Can you share an image tag or preview environment link where I can test it?

[ThorbenLindhauer]

@ArezooAzar you can test with snapshot images as the fix has been merged to main

@ThorbenLindhauer : Thank you for your reply. There were some issues with the snapshot earlier, but they have been resolved now. I tested it in the SaaS environment.

Looks good! Can we mark the issue as done?

EDIT: Confirmed QA is done with @ArezooAzar on Slack, so this issue can be marked as Done.
