jsf - UserWizard 中具有动态值选择查询的可编辑数据表

Question

启动.xhtml

我正在使用 primefaces 向导来显示应用程序的顺序流程。在成员详细信息选项卡之一中，我有一个可编辑的数据表。对于名称列，我希望用户从可用的用户列表中选择名称单击按钮时具有名称，名称，部门

我在单击按钮时在对话框中使用另一个数据表。

但是如何在单击添加按钮后更新原始数据表中的选定值。

      <h:body>
        <h:form id="compositionmaster">
            <p:growl id="growl" sticky="true" showDetail="true"/>
