因此，这与经常被问到的“如何将消息呈现到多个表单”相反。我在一页上有两个表单，在一个表单中验证后，摘要错误（如果验证失败）显示在提交按钮下方的两个表单上。如果代码成功发送所需的电子邮件，则确认消息也会以两种形式显示。它们应该只显示在提交的表单中。inputTexts 下面的消息可以正常工作。我究竟做错了什么？

使用<p:commandButton>外观更新。所以试试这个：

<p:commandButton id="id_remindUsernameButton" value="Retrieve Username" 
   action="#{credentialsManagementBean.rememberUsername}" update="id_UserReminderMessage" process="@form">
</p:commandButton>

默认是<p:commandButton>ajax提交，不需要<f:ajax>
