我有一個數據表,它具有添加編輯刪除和過濾操作。添加操作後PrimeFaces數據表不能正確刷新
所有操作都在數據庫上正常工作,但數據表在添加操作後未正確更新。
它在第一次添加操作後正確更新。 當我添加第二行時,數據表被更新,但是首先添加的行被替換爲第二行添加的行,但在數據庫中它們被正確更新。
同樣,當我添加第3行第1行被替換爲第3行。在CRUD dataTable的應用程序中使用
軟件堆棧是: - PrimeFace 3.4.2,JSF 2.1,NetBeans的7.2.1,Java的GlassFish的1.6.0_37 3.1.X,MySql的5.x的
這是我的代碼。

我通過以下鏈接使用Lawyno建議的代碼解決了我的問題: http://forum.primefaces.org/viewtopic.php?f=3&t=11389&hilit=dialog+open&start=20 現在表格是在添加操作後正確更新。 – jahnavi
你應該添加這個答案和細節並接受它! –
