如何在弹出式面板中提交值？

Question

我有很难理解如何以正确的方式使用rich:popupPanel组件.有(至少不是我能找到的)关于如何使用rich:popupPanel以及如何从中提交值的帖子.

更糟糕的是,面板接缝要添加(当检查html时)一个硬编码的"_content"到它的组件ID名称(生成的div).我试图使用aj4:region标签来部分呈现完整的表单.但是这没有发挥作用,因此没有任何内容发布到托管bean.所以现在我有一个选项,其中面板有自己的形式,在页面上的主要形式之外.

我可以看到形式(弹出)值的评估正在发生,但不会执行持久化值的bean函数(我看到命令按钮的POST请求).我现在能想到的唯一原因是,弹出式面板使用另一个bean来持久保存页面上主要表单的值(两者都是会话作用域).我正在考虑一起省略弹出式面板,因为它很难完成这项工作.也许这是一个众所周知的秘密,因为关于它的帖子很少.如果使用componentController或仅使用a4j:commanLink,它的行为相同.

如何从rich:popupPanel提交值并调用支持bean函数来保持弹出窗体值？

感谢有人可以对此有所了解,问候克里斯.

我在Glassfish 3.1上使用Richfaces 4.0-final

<h:form id="main_form">
<!-- Command for popup -->
<a4j:commandLink actionListener="#{userController.prepareCreateSysRequest}" oncomplete="#{rich:component('popup_sys_user_req_form:popup_sys_user_req')}.show(); return false;" 
                                     execute="@this" value="Request New Sector/Category" />

    ...
<a4j:commandButton action="#{projectController.Create}" ...>
</h:form>

<h:form id="popup_sys_user_req_form">
    <rich:popupPanel id="popup_sys_user_req" modal="true" autosized="true" resizeable="false">
        <f:facet name="header">
            <h:outputText value="New Project Request" />
        </f:facet>
        <f:facet name="controls">
            <h:outputLink value="#"
                          onclick="#{rich:component('popup_sys_user_req')}.hide(); return false;">
                X
            </h:outputLink>
        </f:facet>
        <h:panelGrid columns="2">
            <h:outputLabel value="Request New:" />
            <h:selectOneMenu id="sys_req_type" value="#{userController.selectedSysRequestType}" required="true" requiredMessage="Request Type is required" title="Request Type">
                <f:selectItems value="#{userController.getSysRequestTypeItems()}">
                </f:selectItems>
            </h:selectOneMenu>
            <h:outputLabel value="Description:" />
            <h:inputTextarea id="user_req_desc" value="#{userController.selectedSysUserRequest.description}" required="true" requiredMessage="Decription is missing" />
        </h:panelGrid>
        <a4j:commandButton action="#{userController.CreateSysUserRequest}" onclick="#{rich:component('popup_sys_user_req')}.hide(); return false;" execute="@form" render="popup_sys_user_req_form" value="Send Request" />
    </rich:popupPanel>
</h:form>

对于我所做的事情,我曾经有过这个问题,只能在第一次提交两次.

要修复它,表单必须在popupPane之外.而且popupPanel应该有atopbute domElementAttachment ="form".

例.

        <h:form>
            <rich:popupPanel id="shipmentItemUpdateDialog" 
                             autosized="true"
                             domElementAttachment="form">
                <f:facet name="header">
                    <h:panelGroup>
                        <h:outputText value="#{shipmentBundle.shipmentItemDetailsHeader}" />
                    </h:panelGroup>
                </f:facet>
                <f:facet name="controls">
                    <h:commandLink>
                        <h:graphicImage value="/core/images/modal/close.png"/>
                        <rich:componentControl target="shipmentItemUpdateDialog" operation="hide" />
                    </h:commandLink>
                </f:facet>
                <h:outputText for="shipmentItemName"
                              value="#{coreBundle.requiredChar} #{shipmentBundle.shipmentItemName}"
                              />
                <h:inputText id="shipmentItemName" 
                             disabled ="false"
                             required ="true"
                             value="#{shipmentItemController.shipmentItemUI.value.name}" 
                             label="#{shipmentBundle.shipmentItemName}"

我希望这有帮助.
