在我的 bean 被持久化之前，我想验证几个字段。
我有 inputText，selectOne，SelectManyListBox，...
我的问题是，对于其中一些人来说，验证已经完成，而对于另一些人来说，没有......
例如。我有
<tr>
<td><h:outputLabel value="#{msg.subscriptionFormFieldPhone}:" /></td>
<td><h:inputText
id="phone"
value="#{detailModel.afterObject.phone}"
disabled="#{detailModel.mode == detailModel.viewMode or (detailModel.mode == detailModel.editMode and !loggedUser.hasPermission('CMN backoffice permission id'))}" />
<h:messages for="phone" style="color:red; font-size:12px;" />
</td>
</tr>
...
<tr>
<td><h:outputLabel value="#{msg.subscriptionFormFieldFund}:" /></td>
<td>
<table>
<tr>
<td><h:inputText
id="fund"
value="#{detailModel.afterObject.fund}" disabled="true">
<f:converter converterId="ch.ethz.id.cmn.FundConverter" />
</h:inputText>
<h:messages for="fund" style="color:red; font-size:12px;" />
</td>
<td valign="top">
<!-- add button -->
<h:commandButton styleClass="waiButton"
value="#{lakshmiMsg.commonButtonAddExisting}"
action="#{detailController.gotoFundSelection()}"
rendered="#{(detailModel.mode == detailModel.createMode and detailModel.afterObject.fund == null) or ((detailModel.mode != detailModel.viewMode and detailModel.afterObject.fund == null))}"
disabled="#{detailModel.mode == detailModel.multiEditMode}" />
<!-- delete button -->
<h:commandButton styleClass="waiButton"
value="#{lakshmiMsg.commonButtonDelete}"
action="#{detailController.deleteFund()}"
rendered="#{((detailModel.mode == detailModel.editMode) and loggedUser.hasPermission('CMN backoffice permission id')) or (detailModel.mode == detailModel.createMode and detailModel.afterObject.fund != null)}"
disabled="#{detailModel.mode == detailModel.multiEditMode}" />
</td>
</tr>
</table>
</td>
</tr>
<tr>
<td><h:outputLabel value="#{msg.subscriptionFormFieldOwner}:" /></td>
<td>
<table>
<tr>
<td><h:inputText id="owner"
value="#{detailModel.afterObject.owner}"
disabled="true">
<f:converter converterId="ch.ethz.id.cmn.UserConverter"></f:converter>
</h:inputText>
<h:messages for="owner" style="color:red; font-size:12px;" />
</td>
<td valign="top">
<!-- add button -->
<h:commandButton styleClass="waiButton"
value="#{lakshmiMsg.commonButtonAddExisting}"
action="#{detailController.gotoUserSelection()}"
rendered="#{(detailModel.mode == detailModel.createMode and detailModel.afterObject.owner == null) or ((detailModel.mode != detailModel.viewMode and detailModel.afterObject.owner == null))}"
immediate="true"
disabled="#{detailModel.mode == detailModel.multiEditMode}" />
<!-- delete button -->
<h:commandButton styleClass="waiButton"
value="#{lakshmiMsg.commonButtonDelete}"
action="#{detailController.deleteOwner()}"
rendered="#{((detailModel.mode == detailModel.editMode) and loggedUser.hasPermission('CMN backoffice permission id')) or (detailModel.mode == detailModel.createMode and detailModel.afterObject.owner != null)}"
immediate="true"
disabled="#{detailModel.mode == detailModel.multiEditMode}" />
</td>
</tr>
</table>
</td>
</tr>
...
<tr>
<td valign="top">
<h:outputLabel value="#{msg.subscriptionFormFieldDataOptions}:" /></td>
<td>
<table>
<tr>
<td>
<h:selectManyListbox
id="dataOptions"
value="#{detailModel.selectedDataOptions}"
size="5"
disabled="#{detailModel.mode == detailModel.viewMode or (detailModel.mode == detailModel.editMode and !loggedUser.hasPermission('CMN backoffice permission id'))}">
<f:selectItems value="#{detailModel.afterObject.dataOptions}"
var="sdo" itemLabel="#{sdo.dataOptionName}"
itemValue="#{sdo}" />
</h:selectManyListbox>
<h:messages for="dataOptions" style="color:red; font-size:12px;" />
</td>
...
</tr>
</table>
</td>
</tr>
...
在我的bean（与detailModel.afterObject 绑定）中，我用@NotNull 和@Size(min=1) 标记了这些字段。
@NotNull( message = "{validation.emptyPhoneNumber}" )
@Pattern( regexp = "^(((41)(\\s?)(-?))|(0))(7)(\\d{1})(\\s?)(-?)(\\d{3})(\\s?)(-?)(\\d{2})(\\s?)(-?)(\\d{2})", message = "{validation.notValidPhoneNumber}" )
private String phone;
@NotNull( message = "{validation.emptyFund}" )
@Size(min=1, message = "{validation.emptyFund}" )
private String fund;
@NotNull( message = "{validation.emptyOwner}" )
@Size(min=1, message = "{validation.emptyOwner}" )
private String owner;
@ManyToMany( fetch = FetchType.LAZY, cascade = {} )
@JoinTable( name = "CMN_MAP_SUBSCRIPTION_TO_DATAOPTION" )
@NotNull( message = "{validation.emptyDataOption}" )
@Size(min=1, message = "{validation.emptyDataOption}" )
private Set< DataOption > dataOptions;
好吧，第一个 inputText （电话）已经过验证，如果我把它留空或模式不匹配，我会收到错误消息，但对于其他人来说，（显然）没有验证；如果我将它们留空，则不会出现任何消息...
唯一的区别是对于基金和所有者的 inputFileds 有一个转换器，最后一个是一个 selectManyListBox，它映射到一个 Set，而所有其他的都映射到 String。
由于持久性随后失败，我在日志中有一条错误消息，并且在那里我可以看到一个 ConstraintViolationException，但我不明白为什么它在验证时没有声称在页面上显示消息而不是堆栈跟踪日志...

欢迎帮助，提示，提示......
更新：
我在手机 inputText 和资金 inputText 中编写并添加了一个 Validator：
<f:validator validatorId="ch.ethz.id.cmn.validator.SubscriptionValidator" />
我在 validate 方法中设置了一个断点。
好吧，对于电话来说，方法是调用，对于基金来说不是！
我很困惑。我的 html 代码中的某些内容阻止了验证...
更新 2：
如果我删除disabled="true"，它会起作用。它是如此想要还是一个错误？如果该字段被禁用，有没有办法让它工作？
更新 3：
现在我真的很困惑......在用 readonly all （但 selectManyListBox ）替换 disabled 之后，它工作得很好，直到我在持久化页面后尝试编辑页面中的某些值。尽管我没有更改/删除fund 和owner 字段，但我收到了验证错误消息...我在bean 的getters 方法中放置了一个断点，并且设置了值，即不为null。那么为什么@NotNull 仍然抱怨呢？如果我删除 bean 中的注释并在 html 中添加 required 和 requiredMessage ，也会发生这种情况。
