Duplicate text in <p:messages> summary and detail
提问by Seitaridis
When the email address is invalid the message displayed is "Invalid email.Invalid email.". I know that the message has two parts: summary and a details. I need both of these, but I want to have different info in each. How can I change the message to display "Invalid email: Please enter a valid email address" instead?
当电子邮件地址无效时，显示的消息是“电子邮件无效。电子邮件无效。”。我知道该消息有两部分：摘要和详细信息。我需要这两个，但我希望每个都有不同的信息。如何更改消息以显示“无效的电子邮件：请输入有效的电子邮件地址”？
<p:messages showDetail="true" autoUpdate="true" closable="true" />
<h:panelGrid columns="2">
<h:outputText value="#{label.email}: *" />
<p:inputText required="true" value="#{userWizard.emailAddress}"
validatorMessage="#{label.invalidEmail}" label="#{label.email}">
<f:validateRegex pattern="^[_A-Za-z0-9-\+]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$">
</f:validateRegex>
</p:inputText>
</h:panelGrid>

This is not possible with validatorMessage(neither converterMessagenor requiredMessage). The value will be used as boththe summary and the detail.
这是不可能的validatorMessage（既不是converterMessage也不是requiredMessage）。该值将被用作既总结和细节。
You'd need to homegrow a custom validator instead wherein you can construct the FacesMessagewith the both parts yourself. Assuming that you've next to the label.emailalso a label.email_detailwhich represents the message detail, then it should look something like this:
你需要homegrow一个自定义的验证，而不是其中您可以构建FacesMessage与两个部分自己。假设您旁边label.email还有label.email_detail代表消息详细信息的 a ，那么它应该如下所示：
@FacesValidator("emailValidator")
public class EmailValidator implements Validator {
private static final Pattern PATTERN = Pattern.compile("([^.@]+)(\.[^.@]+)*@([^.@]+\.)+([^.@]+)");
@Override
public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
if (value == null || ((String) value).isEmpty()) {
return; // Let required="true" handle.
}
if (!PATTERN.matcher((String) value).matches()) {
String summary = context.getApplication().evaluateExpressionGet(context, "#{label.email}", String.class);
String detail = context.getApplication().evaluateExpressionGet(context, "#{label.email_detail}", String.class);
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, summary, detail));
}
}
}
(note that I adapted the email regexp for better preparation on world domination; non-latin characters like Chinese, Hebrew, Cyrillic, etc are namely allowed in domain names and thus also email addresses since the new IANA decision in 2010)
（请注意，我修改了电子邮件正则表达式，以便更好地为统治世界做好准备；自2010 年 IANA 做出新决定以来，域名和电子邮件地址中都允许使用中文、希伯来语、西里尔文等非拉丁字符）
which is then to be used as
然后将其用作
<p:inputText ... validator="emailValidator" />

According to the documentation here : http://www.primefaces.org/docs/vdl/3.4/primefaces-p/messages.html
根据这里的文档：http: //www.primefaces.org/docs/vdl/3.4/primefaces-p/messages.html
You could do something like that :
你可以这样做：
<p:messages showSummary="true" showDetails="true" />
You can also put them apart... for styling :
您也可以将它们分开...用于造型：
<p:messages showSummary="false" showDetails="true" />
<p:messages showSummary="true" showDetails="false" />
But you can't define the two error messages with validatorMessage :
但是您不能使用 validatorMessage 定义两个错误消息：
