我是新手，我的英语不是很好。我已经生成了一个数据表，当我点击数据表视图按钮时，一个带有backingbean数据的模型diloag框将出现。我的问题是我的diloag没有显示来自backingbean的当前数据。但是当我通过访问url刷新页面时，它会显示我以前的数据。我在这里添加了μ代码和支持豆，请帮助
我的.xhtm是

我正在添加负责我的dilog框的代码。我是stackoverflow的新手，所以我不太容易放置我的代码。我的bean在会话范围内，方法读取readFormStatus（id）从数据库获取数据，并在我的支持bean上设置数据。
请帮忙，提前感谢
我认为您只需要添加
update=":data"
在显示对话框的按钮上。
您刷新了bean上的数据，但从未告诉对话框使用这些刷新的数据进行更新。
<p:commandLink>上的"update"属性确实可以实现。但我认为，如果你想更新以下表格的内容
<h:form class="form-horizontal" id="data">
你实际上必须更新对话框
<p:dialog widgetVar="test" id="dialog" height="600" width="760">
所以基本上，你的commandLink应该是这样的
<p:commandLink value="View" update=":dialog" action="#examinationFormBean.readFormStatus(test.id)}" oncomplete="PF('test').show()">
