JSF 数据表，战斧收音机

Question

我试图在我的 rich:datatable 中使用 t:radio，但它总是抱怨找不到组件。我做了一些谷歌搜索，我必须声明全名，但我实际上认为我正在这样做。

谁能指出我做错了什么？代码（我不打算给出一个缩小版本，因为我猜它的组合出了问题）：

letterDetailTemplate.xhtml:

<h:form id="generateLetterForm">
    <ui:include src="addStandardLetterMain.xhtml" />
    <ui:include src="addStandardLetterText.xhtml" />
    <ui:include src="buttons.xhtml" />
</h:form>

addStandardLetterText.xhtml（单选按钮在此处，在 slrDataTable 中）：

        <div class="rButtonPanel">

                <a4j:ajax event="click" execute="generateLetterForm"
                    listener="#{entityBB.addMotivationToReport}"
                    oncomplete="#{rich:component('addStandardLetterRegion')}.hide()"
                    render="reportMotivationTextPanel" limitRender="true" />
            </h:commandButton>
            <a4j:commandButton value="#{AppMessages['general.action.cancel']}"
                onclick="#{rich:component('addStandardLetterRegion')}.hide()"
                limitRender="true" immediate="true" bypassUpdates="true" />
        </div>
    </rich:popupPanel>
</l:screenzone>

请注意，当我删除 t:radio 时，此视图可以工作并呈现和显示来自 backingbean 的数据。

我得到的错误信息是：

SEVERE: java.lang.IllegalStateException: Could not find component 'generateLetterForm:slrDataTable:slrOption' (calling findComponent on component 'generateLetterForm:slrDataTable:0:j_idt258')
javax.faces.FacesException: java.lang.IllegalStateException: Could not find component 'generateLetterForm:slrDataTable:slrOption' (calling findComponent on component 'generateLetterForm:slrDataTable:0:j_idt258')

Answer 1

将 for="generateLetterForm:slrDataTable:slrOption" 更改为 for=":generateLetterForm:slrOption" 并在数据表中为您的 t:radio 指定 id。不要忘记 generateLetterForm 之前的“:”。
