在primeFaces上的dataTable中编辑其他信息

Question

所以，我的页面上有一个dataTable，它显示了一些基本信息和行扩展，以显示额外的信息。我正在尝试创建一个按钮/上下文菜单来显示一个对话框，以便用户可以编辑表格上的信息（基本和额外的，所有形式），但我从表中获取这些数据时遇到了麻烦。当我单击按钮显示对话框时，它只显示第一行的信息，而不是我选择的行。有任何想法吗？谢谢。代码如下。

 <p:dataTable id="socios" var="socio" value="#{sociosBean.socios}" rowKey="#{socio.id}"   
                         selection="#{sociosBean.socioEscolhido}" selectionMode="single" paginator="true"
                         widgetVar="socios" emptyMessage="Nenhum socio encontrado " filteredValue="#{sociosBean.socioFiltro}" 
                         rows="10" paginatorAlwaysVisible="false">

我猜测问题是你在显示时没有更新对话框的内容。因此，您必须将update="editarSocio:cadastro"添加到用于显示对话框的commandButton中。 但请注意，您必须输入的ID取决于XHTML的结构，我不知道。
