我正试图从这个PrimeFaces ShowCase中描述的bean中显示一个对话框.事情是一切按预期工作,对话框显示,但如果我关闭对话框然后再次按下按钮,除非页面刷新,否则对话框不会显示.
这不是示例中显示的行为,每次按下按钮时,对话框都会出现.
我在代码中唯一的区别是我使用了CDI替代品而不是托管bean包,因为javax.faces.bean包将被弃用.我的意思是:
javax.inject.Named 代替 javax.faces.bean.ManagedBeanjavax.faces.view.ViewScoped 代替 javax.faces.bean.ViewScoped在任何情况下,我也尝试过托管bean包,但仍然是相同的错误行为.
这是我到目前为止:

我尝试过使用Mozilla Firefox,Google Chrome和MS IE11.

此错误在此处报告PF 4.0.10及更高版本中的对话框架回归错误和问题6915:关闭从DataTable打开的DF窗口时PF 5.0错误
作为一种解决方案,使用taconic的解决方案,即在体内添加面板.
你的dialog.xhtml看起来像这样:
