Tampilan daftar metode getListItemXmlAttributes gagal dengan item publikasi anak


358

Saya telah membuat kelas JS untuk mengisi data tampilan daftar SG / Folder, ketika item diubah. ( Sesuai pendekatan Jaime) Semuanya berfungsi dengan baik ketika saya mengoperasikan item dalam publikasi tempat mereka dibuat.

Mis: Saya membuka komponen atau halaman dan locked bykolom kustom segera memperbarui dan menunjukkan nama pengguna saya.

Namun, ketika saya pergi ke publikasi anak dan mengulangi proses itu, saya mendapatkan jendela menanyakan apakah saya ingin melokalisasi atau mengedit item induk. Jika saya memilih untuk mengedit jendela induk, kode tidak berfungsi. Saya belum menemukan jawabannya dengan debugging awal. Chrome tampaknya menelan kesalahan, Firefox memberi saya samar:

Cap waktu: 6/22/2012 3:42:54 PM

Kesalahan: pengecualian tanpa tertangkap: [Pengecualian ... "Komponen mengembalikan kode kegagalan: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOINTERFACE)" lokasi: "JS frame :: chrome: // browser / content / tabbrowser .xml :: :: baris 545 "data: tidak]

Adakah yang punya ide awal? Saya akan mencoba memposting beberapa kode nanti ...

Saya mendapatkan pesan kesalahan seperti itu paling sering dari memasukkan sesuatu ke DOM secara ilegal. Ada pembaruan pada kode itu? Tanpa itu akan sangat sulit untuk memberi Anda jawaban yang lebih konkret.

Biarkan saya melihat bagaimana saya dapat memposting kode. ini cukup besar. Saya akan mencoba untuk memangkas hal-hal yang tidak relevan jika saya bisa. Saya tidak mendapatkan kesalahan dalam log di server CME. Firefox adalah satu-satunya browser yang memberikan kesalahan. yang lain tidak menunjukkan kesalahan, jangan isi kolom "khusus" dengan data.

Ini saat ini belum terselesaikan di Bugzilla . Kode mozilla yang relevan

Ini mungkin tidak ada hubungannya dengan itu, tetapi di initializer kelas MyCompany.Tridion.RTFExtensions.PageExAnda untuk Anda mengatur semuanya undefined. Ini dapat menyebabkan masalah saat Anda mendefinisikan atribut lalu mengatakannya bahwa itu tidak terdefinisi - yang tidak masuk akal. Lebih baik mengatur nilai awal nulljika Anda tidak menginginkan nilai. Seperti yang saya katakan ini mungkin tidak masalah, kecuali kode lain sedang memeriksa kunci yang ditentukan ..

Mungkin ini bisa membantu: w3schools.com/js/js_strict.asp Juga, ini mungkin tidak memperbaiki masalah Anda, tetapi satu-satunya undefinedpemeriksaan yang saya lihat bekerja typeof something === 'undefined'dengan ===, ==,! =, Atau! == Juga, Anda dapat mencoba menggunakan setTimeout untuk mengeksekusi setXml setelah getOuterXml

[Pengecualian ... "Komponen mengembalikan kode kegagalan: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]"

Ini berarti bahwa tidak ada jendela yang ditetapkan untuk objek nsIWebProgress . Jadi tidak ada tempat untuk menampilkan data.

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

Ini memberi tahu Anda file apa yang terkait dengan kesalahan itu. dan baris apa yang salah.

Tetapi kunci sebenarnya adalah kesalahan NS_NOINTERFACE. Yang berarti antarmuka belum terdaftar.

Anda menggunakan Type.enableInterface(). Apakah itu metode khusus yang Anda deklarasikan di tempat lain? Saya tidak melihatnya. Anda mungkin ingin mengubahnya menjadi.registerInterface()
