einführen

Ein kleiner Fehler in Serie 2 hat heute Benutzereingaben hinzugefügt, Benutzermodule hinzugefügt, Benutzer gelöscht und Benutzermodule geändert.

Der folgende Code ist eine Klasse, die zu Serie 2 geändert oder hinzugefügt wurde.

Schauen wir uns zunächst die Modifikation der Addpanel -Klasse an:
Das Verhindern des Fehlers beim Sammeln von Parametern kann dies verhindern.
