包含形式的复合组件存在的问题 [英] Problems with composite components that include form

问题描述

我正在编写一个复合组件，例如复杂的输入文本，它需要一个完整的表单(它将显示一个搜索表单，并且一个结果列表供用户选择其中之一).

I am writing one composite component like a complex inputtext, that requiere a complete form (it will show a search form and one list of results for the user selects one of them).

<composite:implementation>
    <div id="#{cc.clientId}" class="#{cc.attrs.styleClass}">
        <h:inputText id="txtIdentificador" ...>
        <h:graphicImage id="imgIdentificador" ...>
        <h:inputText id="txtDescripcion" ...>
        <h:form id="formF2ItemWidget">
        ...
        </h:form>
    </div>
</composite:implementation>

从逻辑上讲，我想使用其他形式，但是这样做时会遇到问题.例如

Logically, I would like to use into other form, but I have problems when I do it. e.g.

<h:form id="formOuter" >
    <h:outputLabel value="Texto1" />
    <trkal:itemwidget id="txtTexto1">
    ...
</h:form>

生成的HTML没有内部表单(formF2ItemWidget)，仅具有id = formOuter的表单.但是在下面的示例中:

The HTML generated hasn't the inner form (formF2ItemWidget), it only has the form with id=formOuter. But in the below example:

<h:form id="formOuter" >
    <h:outputLabel value="Texto1" />
    <trkal:itemwidget id="txtTexto1">
    <h:outputLabel value="Texto2" />
    <trkal:itemwidget id="txtTexto2">
    ...
</h:form>

txtTexto1的表单不存在，但是txtTexto2的表单存在.为什么?

The form for txtTexto1 don't exist, but the form for txtTexto2 exists. Why?

如何编写包含表单的复合组件，而不会出现此问题?

How can I write a composite component that include a form without this problem?

我正在使用mojarra 2.1.7，Java 6.0和Tomcat 7.0

推荐答案

嵌套<form>元素在HTML中是非法的.由于JSF只是HTML代码生成器，因此您无法在此处使用JSF进行任何魔术操作.

Nesting <form> elements is illegal in HTML. As JSF is merely a HTML code generator, you can't do any magic with JSF here.

不要也将<h:form>组件嵌套在JSF中.从组合中删除该<h:form>，并寻找处理子表单"的替代方法.

Just don't nest <h:form> components in JSF as well. Remove that <h:form> from the composite and look for alternate ways to process the "sub-form".
