Test

• Neue App anlegen.
• Neuen Typ A erstellen.
• In Instanzen-Admin wechseln.
• Neue Zeile anlegen, nicht übernehmen, nicht speichern.
• Kontext-Menü auf der neuen Zeile öffnen.
• Erwartung: Löschen-Knopf wird nicht angezeigt, oder ist ausgegraut, oder gibt bei Auswahl eine vernünftige Meldung statt einer UnsupportedOperationException mit Internal-Error.
