看起来你遇到了这个问题：

How can I populate a text field using PrimeFaces AJAX after validation errors occur?

将faces-config.xml与OmniFaces库一起添加到您的select-one-menu正确更新inputField

<lifecycle>
    <phase-listener>org.omnifaces.eventlistener.ResetInputAjaxActionListener</phase-listener>
</lifecycle>

如果您不想为所有组件执行此操作，OmniFaces会展示如何为每个组件执行此操作：http://showcase.omnifaces.org/eventlisteners/ResetInputAjaxActionListener

提交ajax后的primefaces不会更新
