Omnifaces validateBean:无法使showMessageFor服装正常工作 [英] Omnifaces validateBean: can not get showMessageFor attirbute to work

问题描述

我正在使用 Omnifaces <o:validateBean /> 在类级别约束下使用JSR303 bean验证.我的问题是基于以前关于如何将消息附加到特定组件的问题.从Omnifaces 2.6开始，有一个showMessageFor属性可以完全解决我当时的问题(非常感谢Omnifaces库的开发人员;-).我的问题是我无法使用它.

这是我的设置.我有三个输入字段，其中两个在类级别约束中耦合(weddingDay必须小于silverWeddingAnniversary；如有必要，我可以附加更多代码).

@DayIsBeforeAnniversary
@Entity
public class Person implements Serializable
{
    private String name;

    @Temporal(TemporalType.DATE)
    private Date weddingDay;

    @Temporal(TemporalType.DATE)
    private Date silverWeddingAnniversary;
    ...
}

<h:form id="main_form">
    <p:messages />

    <p:outputLabel value="Name" for="id_name" />
    <p:message for="id_name" />
    <p:inputText id="id_name" value="#{personController.person.name}" /><br />

    <p:outputLabel value="Wedding Day" for="id_wedding" />
    <p:message for="id_wedding" />
    <p:calendar id="id_wedding" value="#{personController.person.weddingDay}"  /><br />

    <p:outputLabel value="Silver Wedding Anniversary" for="id_anniversary" />
    <p:message for="id_anniversary" />
    <p:calendar id="id_anniversary" value="#{personController.person.silverWeddingAnniversary}"  /><br/>

    <p:commandButton 
        value="test" 
        action="#{personController.navigate()}" 
        update="@all"/>

    <o:validateBean 
        value="#{personController.person}" 
        showMessageFor="id_wedding id_anniversary" />
</h:form>

所以我的目的是在与我指定了ID(showMessageFor="id_wedding id_anniversary")的两个<p:calendar/>标签相对应的<p:message/>标签中显示验证消息.

实际结果有所不同.常规<p:messages/>标记中显示两个消息.并且所有输入字段都以红色突出显示(甚至是名称的输入；每个输入和标签都具有class ="ui-state-error").实际上，当我完全忽略showMessageFor属性时，没有什么区别(除了<p:messages/>中仅呈现一条消息).

那么我该怎么做才错呢?如何指示错误消息出现在两个特定的<p:message/>标记中?如何防止无关名的输入字段变成红色?

解决方案

问题是2折.

1. showMessageFor属性无意中将客户端ID解释为完整的客户端ID.下面的方法将为您工作.

   <o:validateBean 
       value="#{personController.person}" 
       showMessageFor="main_form:id_wedding main_form:id_anniversary" />
   

2. showMessageFor不用于仅将特定输入字段标记为无效.不幸的是，除了获取 <o:validateOrder> 之外，没有其他解决方法.

   <o:validateOrder
       components="id_wedding id_anniversary"
       message="You cannot celebrate wedding anniversary before being married"
       showMessageFor="@all" />
   

两个问题均已根据 issue 446 修复. >

I am using Omnifaces <o:validateBean /> to use JSR303 bean validation with a class level constraint. My question is based on a former question about how to attach message to specific components. Since Omnifaces 2.6 there is a showMessageFor attribute which solves my question at that time completely (so big thanks to the developers of Omnifaces library ;-). My problem is that I can not get it to work.

Here is my setting. I have three input fields, two of them are coupled in a class level constraint (weddingDay must be smaller than silverWeddingAnniversary; I could attach more code if necessary).

@DayIsBeforeAnniversary
@Entity
public class Person implements Serializable
{
    private String name;

    @Temporal(TemporalType.DATE)
    private Date weddingDay;

    @Temporal(TemporalType.DATE)
    private Date silverWeddingAnniversary;
    ...
}

<h:form id="main_form">
    <p:messages />

    <p:outputLabel value="Name" for="id_name" />
    <p:message for="id_name" />
    <p:inputText id="id_name" value="#{personController.person.name}" /><br />

    <p:outputLabel value="Wedding Day" for="id_wedding" />
    <p:message for="id_wedding" />
    <p:calendar id="id_wedding" value="#{personController.person.weddingDay}"  /><br />

    <p:outputLabel value="Silver Wedding Anniversary" for="id_anniversary" />
    <p:message for="id_anniversary" />
    <p:calendar id="id_anniversary" value="#{personController.person.silverWeddingAnniversary}"  /><br/>

    <p:commandButton 
        value="test" 
        action="#{personController.navigate()}" 
        update="@all"/>

    <o:validateBean 
        value="#{personController.person}" 
        showMessageFor="id_wedding id_anniversary" />
</h:form>

So my intention is to show the validation message in the <p:message/> tags corresponding to the two <p:calendar/> tags of which I specified the ID (showMessageFor="id_wedding id_anniversary").

The actual outcome is a bit different. Two messages show up in the general <p:messages/> tag. And all input fields are red highlighted (even the input for the name; every input and label has class="ui-state-error"). Actually there is not much difference when I leave out the showMessageFor attribute completely (except there is only one message rendered in the <p:messages/>).

So what am I doing wrong respectivly how can I tell the error messages to appear in the two specific <p:message/> tags and how can I prevent the input field for the uninvolved name to become red?

解决方案

The problem is 2-fold.

1. The showMessageFor attribute unintentionally interprets the client ID as the full client ID. Below approach will work for you.

   <o:validateBean 
       value="#{personController.person}" 
       showMessageFor="main_form:id_wedding main_form:id_anniversary" />
   

2. The showMessageFor isn't used to mark only specific input fields as invalid. Unfortunately, there is no work around for that other than grabbing <o:validateOrder> instead.

   <o:validateOrder
       components="id_wedding id_anniversary"
       message="You cannot celebrate wedding anniversary before being married"
       showMessageFor="@all" />
   

Both issues are fixed in 2.6.9 as per issue 446.
