feat: improve handling of compensation association #2039

smbea · 2023-12-01T08:44:14Z

Allow to connect compensate boundary event to activity, turning it into compensation activity.
Turn sequence flow connected to boundary event into compensation association
when boundary event is turned replaced with compensate boundary event.

Closes #2038

I integration tested this and indeed it feels like an overall less blocking UX, which is a major improvement.

What I found is a couple of quirks:

When transforming to a compensation boundary event the connection turns into an undirected association, where I'd expect a directed association. Expected: We use directed association and the task turns into a compensation task.

Existing sequence flows are not removed, despite being illegal for compensation tasks. Expected: Remove all other existing connections.

Expected: Preview reflects future association layout.

Thanks for looking into this @nikku. I'm going to look into all these details tomorrow

✅ This was a bug fixed via aa2fd41

Expected: Preview reflects future association layout.

drawPreview is being called so I'm still not sure what the issue here is. Will have to look into the connection preview to understand more of how it works. I accept pointers if you have them @nikku 😅

This likely prevents connecting event sub processes to text annotations?

Nope, doesn't affect text annotations

I really like the UX progress you made 🎉

Feels really good. Let's ignore the preview bug for now.

smbea · 2023-12-15T08:36:51Z

Agreed with @barmac that he would take a look at this

barmac · 2023-12-18T15:50:13Z

If there are more than one outgoing sequence flows, we end up with incorrect diagram:

My proposal is to convert only if there is a single sequence flow, and otherwise remove all of the connections.

Another edge case found ;):

There is more:

However, I got the basic interaction to work:

This is an old issue, so I will create a separate issue for this.

barmac · 2023-12-21T08:05:30Z

I retargetted this to develop as it's more a feature than a fix.

nikku · 2023-12-21T12:58:40Z

lib/features/modeling/behavior/CompensateBoundaryEventBehavior.js

+
+      // newSource no longer valid
+      if (isForCompensation(target) && !isCompensationBoundaryEvent(newSource)) {
+        removeIsForCompensationProperty(target);


What scenario did we not cover here?

I am sorry, I don't understand the question. Can you make it more verbose?

This line is not covered by tests, so I wonder which scenario this line represents that we do not not cover through tests.

I will add test cases for that.

This allowed to detect another last bug.

However, this can be recreated only when we forcefully reconnect start. It's not allowed by the rules.

I will leave it out of scope, and remove the respective source code.

lib/features/modeling/behavior/CompensateBoundaryEventBehavior.js

+      if (canBeForCompensation(target) && isCompensationBoundaryEvent(newSource)) {
+        addIsForCompensationProperty(target);


What scenario did we not cover here?

OK so I debugged it and source changes are handled via ReplaceConnectionBehavior. We don't need explicit compensation-specific code.

lib/features/rules/BpmnRules.js

Association removal is handled in CompensateBoundaryEventBehavior.

Thinks look good!

This works great!

nikku · 2023-12-21T16:57:10Z

From my point of view you can go ahead and merge this. Consider cleaning up the commits before.
