El método getListItemXmlAttributes de la vista de lista falla con los elementos de publicación secundarios

He creado una clase JS para llenar los datos de la vista de lista SG / Carpeta, cuando se modifican los elementos. ( Según el enfoque de Jaime) Todo funciona muy bien cuando opero con elementos en la publicación en la que fueron creados.

Ej: abro un componente o página y la locked bycolumna 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 preguntando si quiero localizar o editar el elemento principal. Si selecciono editar la ventana principal, el código no funciona. Todavía no lo he descubierto con la depuración inicial. Chrome parece tragarse el error, Firefox me da una críptica:

Error: excepción no detectada: [Excepción ... "El componente devolvió el código de falla: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOINTERFACE)" ubicación: "JS frame :: chrome: // browser / content / tabbrowser .xml :: :: línea 545 "datos: no]

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

Esto significa que no había una ventana asignada al objeto nsIWebProgress . Por lo tanto, no tiene dónde mostrar datos.

Esto le indica qué archivo está asociado con ese error. y en qué línea falló.

Pero la clave real es el error NS_NOINTERFACE. Lo que significa que la interfaz no ha sido registrada.

Usted está utilizando Type.enableInterface(). ¿Es ese un método personalizado que estás declarando en otro lugar? No lo veo Es posible que desee cambiar eso a.registerInterface()
