Bug: Change in node not applied
Very common issue: You have a workflow with longer execution time (let’s assue 5 minutes). While running this workflow, you check something and find a misconfiguration, e.g. in a Joiner node which was already executed (= green light). You correct this, apply and leave with “OK”.
In such cases, the change is not applied as the workflow is executed. But there is also no message saying exactly this when leaving. So the change is lost and in worse case the user is saving the workflow or pushes it to productiong while thinking the issue is solved.
How you could avoid it:
Disable the “OK” button as it is not allowed in this situation and error-prone (= avoid the error root-case)
Only if above is not possibel: Post an hint / message if the user pushes the OK button in such cases (= do not avoid the root-cause but at least gibes the user a chance)
