Primefaces - Do not display message for required fields, just hightlight border
提问by CountD
I have a Primefaces 3-field form and a <p:messages>tag to show some server-side validation messages. But I don't want to display the client-side messages related to the required="true"option, just highlight the input field with red.
我有一个 Primefaces 3 字段表单和一个<p:messages>标签来显示一些服务器端验证消息。但我不想显示与该required="true"选项相关的客户端消息，只需用红色突出显示输入字段。
Is there a way to do it with Primefaces?
有没有办法用 Primefaces 做到这一点？

You can set <p:messages globalOnly="true"/>, this will just show global messages, which are not attached to any particular field. Also you can user Primefaces' <p:outputLabel/>for label of input elements, it will add error css to input elements.
您可以设置<p:messages globalOnly="true"/>，这将只显示全局消息，不附加到任何特定字段。您也可以使用 Primefaces'<p:outputLabel/>作为输入元素的标签，它将向输入元素添加错误 css。
You should also update form when you do submit. For example if you do that with command button add update="form_id"
您还应该在提交时更新表单。例如，如果您使用命令按钮添加update="form_id"

I did it like this --> rendered="#{not facesContext.validationFailed}"
我是这样做的 -->渲染 =“#{not facesContext.validationFailed}”
<p:messages
rendered="#{not facesContext.validationFailed}"
id="msg"
showDetail="true"
autoUpdate="false"
closable="true" />
