Den Module Creator-Ablauf über ViewSource.OnPackageClick reproduzieren, dabei die gemeldeten Schritte für das C# User-Control-Paket verwenden und die Admin Logs auf die Details der Nullreferenz prüfen. Als abgeschlossen gilt die Aufgabe, wenn die Aktion zum Erstellen des Pakets abgeschlossen wird und ein Installationspaket erzeugt, statt die Meldung über einen kritischen Fehler anzuzeigen.
