Table.xhtml
中有一个primefacesp:datatable
,在使用dialog framework打开对话框的同一页面上有一个p:commandbutton
。与对话框相关的内容位于dialog.xhtml
中。我正在为Table.xhtml
和Dialog.xhtml
使用一个名为TableDialog.java
的支持bean。当对话框关闭时,p:datatable
中的值将使用
<p:ajax event="dialogReturn" listener="#{tableDialog.test}" update = ":form:colors" />
这是Dialog.xhtml

内部p:menuitem
。在互联网上寻找工作时,我在找到了解决方案。上面说
“目前,您可以执行以下操作来解决问题:
menuitem
p:commandbutton
xhtml并添加id=“…”和style=“display:none”
因此,每当我选择一个菜单项时,隐藏按钮就会被执行。非常感谢您的帮助。我在上找到了解决方案
更新版本的Table.xhtml包含
