Liste görünümü getListItemXmlAttributes yöntemi, alt yayın öğeleriyle başarısız oluyor

Öğeler değiştirildiğinde SG / Klasör listesi görünümü verilerini doldurmak için bir JS sınıfı oluşturduk. ( Jaime'nin yaklaşımına göre) Oluşturuldukları yayındaki öğeler üzerinde çalıştığımda her şey harika çalışıyor.

Örn: Bir bileşeni veya sayfayı açıyorum ve özel locked bysütun hemen güncelleniyor ve kullanıcı adımı gösteriyor.

Ancak, bir alt yayına gittiğimde ve bu işlemi tekrarladığımda, pencereyi üst öğeyi yerelleştirmek veya düzenlemek isteyip istemediğimi sorarım. Üst pencereyi düzenlemeyi seçersem kod çalışmaz. İlk hata ayıklama ile henüz tam olarak çözemedim. Chrome hatayı yutuyor gibi görünüyor, Firefox bana şifreli bir şey veriyor:

Zaman damgası: 22.06.2012 15:42:54

Hata: yakalanmayan istisna: [İstisna ... "Bileşen, hata kodu döndürdü: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOINTERFACE)" konum: "JS çerçeve :: chrome: // tarayıcı / içerik / tabbrowser .xml :: :: satır 545 "veri: hayır]
