Widok listy Metoda getListItemXmlAttributes kończy się niepowodzeniem z elementami publikacji podrzędnej

Question

Utworzono klasę JS do wypełnienia danych widoku listy SG/folderu, gdy elementy zostały zmodyfikowane. (As per Jaime's approach) Wszystko działa świetnie, kiedy działają na przedmioty w publikacji są one utworzone w

Np.: otworzyć komponent lub stronę i kolumnę zwyczaj locked by natychmiast aktualizacje i pokazuje moją nazwę użytkownika

.

Jednakże, gdy przechodzę do publikacji podrzędnej i powtarzam ten proces, pojawia się okno z pytaniem, czy chcę zlokalizować lub edytować element nadrzędny. Jeśli wybiorę edycję okna nadrzędnego, kod nie będzie działał. Z początkiem debugowania, który wydaje się przełknąć błąd, Firefox daje mi zagadkę:

[Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]"

Oznacza to, że nie nie było okna przypisanego do obiektu nsIWebProgress. Więc nie ma gdzie wyświetlać danych.

nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome://browser/content/tabbrowser.xml :: :: line 545" data: no]

Informuje o tym, który plik jest powiązany z tym błędem. i w jakiej linii była błędna.

Ale prawdziwym kluczem jest błąd NS_NOINTERFACE. Co oznacza, że ​​interfejs nie został zarejestrowany.

Używasz Type.enableInterface(). Czy jest to niestandardowa metoda, którą deklarujesz gdzie indziej? Nie widzę tego. Może chcesz to zmienić, aby .registerInterface()
