我正在liferay 中开发primefaces portlet。我收到以下错误：

<f:ajax> contains an unknown id 'firstNameField' - cannot locate it in the context of the component firstName

代码片段是：

 <aui:field id="firstNameField" label="#{i18n['first-name']}">
    <p:inputText id="firstName" label="#{i18n['first-name']}" required="true"
    value="#{applicantModelBean.firstName}">
    <f:ajax render="firstNameField"/>

    <p:message id="firstNameMessage" for="firstName"/>
    </p:inputText>
    </aui:field>


**Stack trace is**

不知道是什么<aui:field图书馆

但是，似乎该组件没有将其传递id给生成的HTML，或者它可能会添加一些前缀......

做：查看您生成的 HTML 的源代码... 的 id 是<aui:field什么？尝试在你的f:ajax
