用于 ui 重复输入的 JSF 消息

我有一个 JSF2 应用程序，它使用呈现多个文本框，每个文本框都链接到集合中的一个项目。我需要在单个标记中的输入之后显示错误消息。

同时，我在标记之外还有一些其他必填字段，其中应在其输入旁边显示错误消息，因此它们将具有相应的标记。这里的问题是，每次我触发外部字段的验证时，其消息也会出现在 的标记中。。

代码如下：

<table cellpadding="0" cellspacing="0" width="100%">
    <tr>
        <td><h:outputLabel value="Items"/></td>
        <td>
            <ui:repeat var="i" value="#{itemsBean.itemsCount}" id="items">
                <h:inputText id="itemTitle" value="#{itemsBean.items[i]}" required="true" />
                <h:panelGroup layout="block" styleClass="clear" rendered="#{((i+1) % 10 == 0)}" />
            </ui:repeat>
            <h:messages id="itemsMessages" showDetail="false" showSummary="true" styleClass="error_list" />
        </td>
        <td><h:outputLabel value="Required Field" /></td>
        <td>
            <h:inputText id="requiredField" value="#{itemsBean.requiredField}" />
            <h:message for="requiredField" showDetail="false" showSummary="true" styleClass="error_list" />
        </td>
    </tr>
</table>

我知道这是 JSF 验证的工作方式，但我需要防止外部输入的消息出现在重复项目验证摘要中。提前致谢。

原文

I have a JSF2 application that uses <ui:repeat /> to render a number of text-boxes, each linked to an item in a collection. I need to show the error messages after the inputs in a single <h:messages /> tag.

At the same time, I have some other required fields outside the <ui:repeat /> tag, which
should have its error message next to their input, therefore they will have a corresponding <h:message /> tag. The problem here is that each time I have triggered the outside field's validation, its message appears also in the <h:messages /> tag of the <ui:repeat />.

Here is the code:

<table cellpadding="0" cellspacing="0" width="100%">
    <tr>
        <td><h:outputLabel value="Items"/></td>
        <td>
            <ui:repeat var="i" value="#{itemsBean.itemsCount}" id="items">
                <h:inputText id="itemTitle" value="#{itemsBean.items[i]}" required="true" />
                <h:panelGroup layout="block" styleClass="clear" rendered="#{((i+1) % 10 == 0)}" />
            </ui:repeat>
            <h:messages id="itemsMessages" showDetail="false" showSummary="true" styleClass="error_list" />
        </td>
        <td><h:outputLabel value="Required Field" /></td>
        <td>
            <h:inputText id="requiredField" value="#{itemsBean.requiredField}" />
            <h:message for="requiredField" showDetail="false" showSummary="true" styleClass="error_list" />
        </td>
    </tr>
</table>

I know that this is the way JSF validation works, but I need to prevent the outside input's message from appearing in the repeated items validation summary.
Thanks in advance.
