我正在嘗試使用類似Bootstrap的外觀編寫fileUpload/fileDownload自定義控件。我很滿意這個外觀（見下文）。在Xpages中處理附件時遇到問題
不過，我變得非常不一致的行爲。我非常希望用戶能夠點擊刪除按鈕，並且刪除附件並刷新重複控件。以類似的方式，如果用戶選擇「上傳」，我認爲附件應該上傳到文檔，重複控制也會刷新。
我將附件存儲在與主文檔分開的單個文檔中[它存儲在與代碼分開的數據庫中]。
我正在使用上傳控件的js fileInput庫。
我正在使用重複控制滾動我自己的文件下載查看器。
該代碼適用於某些時間，但並非總是如此。當頁面失敗時，我得到這個錯誤信息（見下文）。
任何建議將不勝感激。
