OmniFaces validateEquals 和复合组件

Question

我将 JSF 2.3 与 Omnifaces 3.0 结合使用。我正在尝试创建一个代表电子邮件文本字段的自定义组件。没什么特别的。

我得到了以下完美运行的代码

<h:form id="formAggiungiUtente">

    <p:outputLabel for="inputTextEmail" value="#{msg['email']}"/>    
    <h:inputText id="inputTextEmail" pt:type="email" value="#{userController.userBean.mail}" class="form-control" required="true" requiredMessage="#{msg['email']} #{msg['campoObbligatorio']}" validatorMessage="#{msg['email']} #{msg['nonValido']}">
        <f:validator binding="#{emailJsfValidator}"/>
    </h:inputText>

    <p:outputLabel for="inputTextSecondEmail" value="#{msg['ripetiMail']}"/>
    <h:inputText id="inputTextSecondEmail" pt:type="email" value="#{userController.secondMail}" class="form-control" required="true" requiredMessage="#{msg['ripetiMail']} #{msg['campoObbligatorio']}" validatorMessage="#{msg['ripetiMail']} #{msg['nonValido']}">
        <f:validator binding="#{emailJsfValidator}"/>
    </h:inputText>

    <o:validateEqual id="equal" components="inputTextEmail inputTextSecondEmail" message="#{msg['indirizziMailDiversi']}" />
</h:form>

在应用程序的其他部分，我需要代表电子邮件文本字段的组件，因此第一步是创建如下内容

<h:form id="formAggiungiUtente">
    <ui:include src="templates/mailTextField.xhtml">
        <ui:param name="id" value="inputTextEmail" />
        <ui:param name="label" value="#{msg['email']}" />
        <ui:param name="value" value="#{userController.userBean.mail}" />
        <ui:param name="required" value="true" />
        <ui:param name="requiredMessage" value="#{msg['email']} #{msg['campoObbligatorio']}" />
        <ui:param name="validatorMessage" value="#{msg['email']} #{msg['nonValido']}" />
    </ui:include>

    <ui:include src="templates/mailTextField.xhtml">
        <ui:param name="id" value="inputTextSecondEmail" />
        <ui:param name="label" value="#{msg['ripetiMail']}" />
        <ui:param name="value" value="#{userController.secondMail}" />
        <ui:param name="required" value="true" />
        <ui:param name="requiredMessage" value="#{msg['ripetiMail']} #{msg['campoObbligatorio']}" />
        <ui:param name="validatorMessage" value="#{msg['ripetiMail']} #{msg['nonValido']}" />
    </ui:include>

    <o:validateEqual id="equal" components="inputTextEmail inputTextSecondEmail" message="#{msg['indirizziMailDiversi']}" />

</h:form>

这里是 mailTextField.xhtml

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml" 
    xmlns:p="http://primefaces.org/ui"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:pt="http://xmlns.jcp.org/jsf/passthrough"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

    <p:outputLabel for="#{id}" value="#{label}"/>    
    <h:inputText 
        id="#{id}" 
        pt:type="email" 
        value="#{value}"
        class="form-control" 
        required="#{required}" 
        requiredMessage="#{requiredMessage}" 
        validatorMessage="#{validatorMessage}">
        <f:validator binding="#{emailJsfValidator}"/>
    </h:inputText>

</ui:composition>

此外，此解决方案有效，但通过阅读大量答案，我了解到如果参数过多，可能需要创建自定义组件。因此，我使用 "cvl" 作为库名称

创建了以下组件

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" 
      xmlns:cc="http://xmlns.jcp.org/jsf/composite"
      xmlns:p="http://primefaces.org/ui"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:pt="http://xmlns.jcp.org/jsf/passthrough">

    <cc:interface>
        <cc:attribute name="label" type="java.lang.String" default="#{msg['email']}" />
        <cc:attribute name="value" type="java.lang.String" />
        <cc:attribute name="required" type="java.lang.Boolean" default="true" />
        <cc:attribute name="requiredMessage" type="java.lang.String" default="#{msg['email']} #{msg['campoObbligatorio']}" />
        <cc:attribute name="validatorMessage" type="java.lang.String" default="#{msg['email']} #{msg['nonValido']}" />
    </cc:interface>

    <cc:implementation>
        <p:outputLabel for="#{cc.clientId}" value="#{cc.attrs.label}"/>    
        <h:inputText 
            id="#{cc.clientId}" 
            pt:type="email" 
            value="#{cc.attrs.value}"
            class="form-control" 
            required="#{cc.attrs.required}" 
            requiredMessage="#{cc.attrs.requiredMessage}" 
            validatorMessage="#{cc.attrs.validatorMessage}">
            <f:validator binding="#{emailJsfValidator}"/>
        </h:inputText>
    </cc:implementation>

</html>

现在我的页面是这样的

<h:form id="formAggiungiUtente">
    <cvl:mailTextField 
        id="inputTextEmail"
        value="#{userController.userBean.mail}"
    />

    <cvl:mailTextField 
        id="inputTextSecondEmail"
        value="#{userController.userBean.mail}"
        requiredMessage="#{msg['ripetiMail']} #{msg['campoObbligatorio']}"
        validatorMessage="#{msg['ripetiMail']} #{msg['nonValido']}"
    />

    <o:validateEqual id="equal" components="inputTextEmail inputTextSecondEmail" message="#{msg['indirizziMailDiversi']}" />
</h:form>

问题是我不知道如何填充 validateEqual 的参数 "components"，因为错误总是如下所示。

ValidateEqual attribute 'components' must refer UIInput client IDs. Client ID is of type 'javax.faces.component.UINamingContainer'

我尝试了很多组合，但都没有成功。我做错了什么？谢谢

Answer 1

by reading a lot of answers I've understood that if there're too many parameter may is the case to create a custom component

这个？ When to use <ui:include>, tag files, composite components and/or custom components?说是创建标签文件，不是自定义组件，更不是复合组件。

如果您使用了标记文件，那么这个结构就可以正常工作。另一方面，复合组件是命名容器。这意味着他们在 children 之上添加了一个额外的客户端 ID 层，就像 <h:form> 和 <h:dataTable> 一样。您还应该在客户端 ID 搜索表达式中包括复合组件自己的 id。它是这样的：

<cc:someComposite id="idOfComposite1" ... />
<cc:someComposite id="idOfComposite2" ... />

<o:validateEqual components="idOfComposite1:idOfInput idOfComposite2:idOfInput" />

复合实现具有：

<h:inputText id="idOfInput" ... />

因此，您只需修复复合组件，使其不再在 child JSF 组件的 id 属性中引用 #{cc.clientId}。这是完全错误的。它应该仅用于包装复合组件实现的普通 HTML <span> 或 <div>，然后使用 Rerendering composite component by ajax.
