Question

我正在开发liferay中的primefaces portlet。我收到了以下错误：

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

代码段是：

 <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**

Answer 1

不确定<aui:field来自哪个库

但是，似乎该组件未将其id传递给生成的 HTML ，或者它可能会添加一些前缀......

执行：查看生成的HTML上的来源... <aui:field的ID是多少？尝试在f:ajax

中使用它

javax.faces.FacesException：<f：ajax>包含一个未知的id - 无法在组件的上下文中找到它</f：ajax>
