EDIT

beim Testen kam ich auf ein Problem, das vielleicht am System, vielleicht an meinen Dateneingaben liegt. Vielleicht siehst Du sofort wo das Problem liegt. Falls nicht, müsste ich noch mehr Beispiele testen, bevor Du zuviel Zeit verlierst.

Ich möchte aus einem neuen Workingset einen existierenden Namen nutzen.
Ich suche die korrigierte Variante aus und bei "Safe" bekomme ich eine Fehlermeldung (unten)

Orthographischen Varianten, ich glaube es war das folgende Pärchen:

http://phycobank.org/102504 Registration on 2020-08-17 13:07:27
Entomoneis annagodhei Al-Handal & Mucko
http://phycobank.org/102503 Registration on 2020-08-17 13:07:25

How to reproduce:

1. start new registration for new reference
2. Choose the validated name Entomoneis annagodhei Al-Handal & Mucko as "existing name"
3. Click "existing name" --> the Name popup editor is being opened in readonly mode
4. Click the save button to close the edior --> NullPointerException:
