Created attachment 183008 [details] File with SmartArt diagram Customize your LibreOffice so that you can access the commands "Edit Diagram" and "Regenerate Diagram". Open the attached file and mark the SmartArt. Click on command "Regenerate Diagram". The diagram is damaged. Reload the file, mark the SmartArt and click on command "Edit Diagram". You get an dialog. Select an item there and click on Remove button. OK. The diagram is damaged. The latter is likely damaged, because it tries to apply a "Regenerate Diagram". Notice, that the commands have no undo action.
My understanding is that Grzegorz Araminowicz initially added very basic smartart editing, perhaps it was even marked as experimental. Then later Armin Le Grand started to take this much further, but that work was aborted due to non-technical reasons. So these commands are not in default menu configs for a reason. Adding them to CC in case they want to comment further. (Edit: can't add g.araminowicz@gmail.com to CC, seems the bugzilla account is deleted.)
Yep, those were supposed to be finished for 7.4 - we can remove/hide them somewhat better on that branch. For master, with the hope that implementation at some stage can continue, I'd suggest we keep them.
