我是新人，我的英语不是那么好。我已经生成了一个数据表，当我点击数据表视图按钮时，会出现一个带有支持bean数据的模型diloag框。我的问题是我的diloag没有显示来自支持bean的当前数据。但是当我通过转到url刷新页面时它将显示我以前的数据。我在这里添加mu代码与支持bean请帮助

我添加了负责我的稀释盒的代码。我是stackoverflow的新手，所以我不能放置我的代码。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。
请帮助，提前致谢
答案 0 :(得分：0)
我认为你只需要添加
update=":data"
。
您刷新bean上的数据，但是您永远不会告诉对话框使用这些刷新的数据进行更新。
答案 1 :(得分：0)
<p:commandLink>上的“更新”属性确实会成功。
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">
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()">
