Question

我有一个简单的项目。当我执行删除或保存等操作时，我的数据表没有更新我所做的。我在采取行动时获取人员名单。我尝试在托管bean类中更新它，但不再工作。

我的JSF页面：

我尝试了每个更新选项。我该如何解决这个问题？谢谢你的帮助。

Answer 1

您不会在任何地方更新“personTable”。从工具栏中更新personList，：userFrm：grid和：frm：personList。

在更新中尝试@（。ui-datatable）（这会更新当前页面上的所有数据表）并查看是否有效。如果是这样，它绝对不是更新问题，而是更新标记中的引用问题，您应该检查是否在任何地方引用了正确的ID。

数据库更新操作在JSF页面中不起作用
