Description Ralf Habacker 2019-07-26 06:35:29 UTC 
STEPS TO REPRODUCE
1. start umbrello
2. add state (or activity) diagram
3. add two states
4. connect states with an association
5. delete the association

OBSERVED RESULT
There is still an association present

EXPECTED RESULT
There should only one association be added

KF5/Qt5 version is irrelevant
Comment 1 Ralf Habacker 2019-07-26 08:05:44 UTC 
> 5. delete the association
This is an issue caused by how the undo framework performs the redo operation. If the widget was not found in the scene, a new widget is created instead of adding the one contained in the undo object to the scene.
