The constraint editor saves (undo, redo) actions for things that do not change anything in the model: 1. Open the Target Access Rule Editor 2. Edit constraint "True" to "And" 3. Execute several times the delete action on the "And" node. (nothing happens!) 4. Now you have to execute several times the "Undo" action until the "And" node is changed back to the "True" node.
