Перелік списку getListItemXmlAttributes не вдається з елементами дочірньої публікації

Я створив клас JS для заповнення даних перегляду SG / Folder, коли елементи змінюються. ( Відповідно до підходу Хайме) Все працює чудово, коли я працюю над елементами публікації, в якій вони створені.

Наприклад: я відкриваю компонент або сторінку, а спеціальний locked byстовпець одразу оновлюється та показує моє ім’я користувача.

Однак, коли я переходжу до дочірньої публікації та повторюю цей процес, у мене з’являється вікно із запитом, чи хочу я локалізувати чи редагувати батьківський елемент. Якщо я вибрав для редагування батьківського вікна, код не працює. Я ще не зовсім зрозумів це з початковою налагодженням. Chrome, здається, поглинає помилку, Firefox дає мені загадку:

Часова позначка: 22.06.2012 15:42:54

Помилка: виняток uncaught: [Виняток ... "Компонент повернув код відмови: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome: // browser / content / tabbrowser .xml :: :: рядок 545 "дані: немає]

Хтось має якісь початкові ідеї? Я спробую опублікувати якийсь код пізніше ...

Це означає, що для об'єкта nsIWebProgress не було призначено вікна . Тож ніде немає даних для відображення.

nsresult: "0x80004002 (NS_NOINTERFACE)" розташування: "кадр JS :: хром: //browser/content/tabbrowser.xml :: :: рядок 545" дані: ні]

Це говорить про те, який файл пов'язаний з цією помилкою. і на якій лінії вона виникла.

Але справжнім ключем є помилка NS_NOINTERFACE. Що означає, що інтерфейс не був зареєстрований.

Ви використовуєте Type.enableInterface(). Це власний метод, який ви декларуєте десь ще? Я цього не бачу. Ви можете змінити це на.registerInterface()
