javascript - El método getListItemXmlAttributes de la vista de lista falla con elementos de publicación secundarios
listview methods (1)
He creado una clase JS para rellenar los datos de vista de lista SG / Carpeta, cuando se modifican los elementos. ( De acuerdo con el enfoque de Jaime) Todo funciona muy bien cuando trabajo en los artículos de la publicación en la que se crearon.
Por ejemplo: abro un componente o una página y la columna locked by personalizada se actualiza inmediatamente y muestra mi nombre de usuario.
Sin embargo, cuando voy a una publicación secundaria y repito ese proceso, aparece la ventana que me pregunta si quiero localizar o editar el elemento principal. Si selecciono editar la ventana principal, el código no funciona. Todavía no lo he resuelto con la depuración inicial. Chrome parece tragar el error, Firefox me da una críptica:

¿Alguien tiene alguna idea inicial? Intentaré publicar algún código más tarde ...

[Excepción ... "El componente devolvió el código de error: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]"
Esto significa que no hubo ventana asignada al objeto nsIWebProgress . Así que no tiene dónde mostrar los datos.
nsresult: "0x80004002 (NS_NOINTERFACE)" ubicación: "JS frame :: chrome: //browser/content/tabbrowser.xml :: :: line 545" data: no]
Esto le indica qué archivo está asociado con ese error. Y en qué línea se ha puesto la falla.
Pero la clave real es el error NS_NOINTERFACE. Lo que significa que la interfaz no ha sido registrada.
Está utilizando Type.enableInterface() . ¿Es ese un método personalizado que estás declarando en otra parte? No lo veo Es posible que desee cambiar eso a .registerInterface()
