提交弹出面板内容,丰富:popupPanel
我正在尝试在另一个具有提交/操作事件的面板内的弹出面板中提交值。但在打开弹出面板之前,我需要在托管 bean 上调用一个函数来创建一个新的实体对象。外部面板具有唯一的 h:form,因为您无法嵌套它们。我已将弹出面板包装在 a4j:region 中,以便在用户提交弹出面板内的值时仅提交这部分。这可以工作,但不能执行弹出面板执行时需要调用的准备函数。我尝试过 a4j:commandLink 但该组件不能与 rich:popupPanel 一起工作(很奇怪,因为它们都是 Richfaces 组件?!)。所以我必须中继 h:commandLink 并使用 ajax。
当打开/呈现弹出面板的链接触发时,如何调用托管 Bean 上的函数?
(正确的模式是什么?)
PS。最初的问题已经改变,但在弹出面板中提交值的问题没有改变。
xhtml 文件的一部分:
<h.form>
...
<a4j:region>
<rich:popupPanel id="popup_sys_user_req" modal="false" autosized="true" resizeable="false">
<f:facet name="header">
<h:outputText value="Request New Sector/Category" />
</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.selectedSysUserRequest.sysrequesttype}" required="true" >
<f:selectItems value="#{userController.getSysRequestTypeItems('SECTOR_CATEGORY')}">
</f:selectItems>
</h:selectOneMenu>
<h:outputLabel value="Description:" />
<h:inputTextarea id="user_req_desc" value="#{userController.selectedSysUserRequest.description(desc)}" required="true" requiredMessage="Decription is missing" />
</h:panelGrid>
<a4j:commandButton action="#{userController.CreateSysUserRequest()}" value="Send Request" execute="sys_user_req_form" oncomplete="#{rich:component('popup_sys_user_req')}.hide(); return false;"/>
</rich:popupPanel>
</a4j:region>
</h:form>
命令链接(重新编辑)
<h:commandLink actionListener="#{userController.prepareCreateSysRequest}" value="Request New Sector/Category">
<f:ajax execute="popup_sys_user_req @this" render="popup_sys_user_req">
<rich:componentControl id="popup_ctr" event="click" target="popup_sys_user_req" operation="show"/>
</f:ajax>
</h:commandLink>
----------------------------
//Managed Bean:
public void prepareCreateSysRequest(ActionEvent event ) {
selectedSysUserRequest = new Sysuserrequest();
JsfUtil.log("Prepare Create System User Request");
}
这篇文章继续讨论有关弹出面板的内容。 问候克里斯。
I am trying to submit values in a pop-up panel inside another panel that has a submit/action event. But before opening pop-up panel I need to invoke a function on my managed bean that create a new entity object. The outer panel has the only h:form, since you can't nest them. I have wrapped the pop-up panel in a a4j:region to submit only this part when the use submits the values inside the pop-up panel. This works, but not the execution of the preparing function that need to be invoked when the pop-up panel executes. I have tried a4j:commandLink but that component don't work together with the rich:popupPanel (strange since both of them are Richfaces components?!). So I have to relay on the h:commandLink and use ajax.
How can I invoke a function on my managed bean when the link to open/render the pop-up panel fires?
(What is the correct pattern for this?)
PS. The initial question has changed, but not the problem concerning submitting values in a pop-up panel.
Part of the xhtml file:
<h.form>
...
<a4j:region>
<rich:popupPanel id="popup_sys_user_req" modal="false" autosized="true" resizeable="false">
<f:facet name="header">
<h:outputText value="Request New Sector/Category" />
</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.selectedSysUserRequest.sysrequesttype}" required="true" >
<f:selectItems value="#{userController.getSysRequestTypeItems('SECTOR_CATEGORY')}">
</f:selectItems>
</h:selectOneMenu>
<h:outputLabel value="Description:" />
<h:inputTextarea id="user_req_desc" value="#{userController.selectedSysUserRequest.description(desc)}" required="true" requiredMessage="Decription is missing" />
</h:panelGrid>
<a4j:commandButton action="#{userController.CreateSysUserRequest()}" value="Send Request" execute="sys_user_req_form" oncomplete="#{rich:component('popup_sys_user_req')}.hide(); return false;"/>
</rich:popupPanel>
</a4j:region>
</h:form>
The commandLink (re-edit)
<h:commandLink actionListener="#{userController.prepareCreateSysRequest}" value="Request New Sector/Category">
<f:ajax execute="popup_sys_user_req @this" render="popup_sys_user_req">
<rich:componentControl id="popup_ctr" event="click" target="popup_sys_user_req" operation="show"/>
</f:ajax>
</h:commandLink>
----------------------------
//Managed Bean:
public void prepareCreateSysRequest(ActionEvent event ) {
selectedSysUserRequest = new Sysuserrequest();
JsfUtil.log("Prepare Create System User Request");
}
This post continues the dicussion about the pop-up panel.

如果我理解正确的话,当您调用 someAction1 时,您希望在 popupPanel 内提交所有表单元素,但不在面板外提交?我可以想到两种方法来做到这一点:
1. a4jcommandButton 有一个 limitToList 属性,可以列出服务器上想要更新哪些组件
2. 在第一个表单之外创建 popupPanel,然后使用它自己的表单:
更新
如果您使用的是 RichFaces 4,您可以将 limitToList 属性替换为 limitRender
If I understand correctly you want to submit all form elements inside popupPanel but not outside the panel when you invoke someAction1? I can think of two ways to do this:
1. a4jcommandButton has a limitToList attribute, you can list which components you want to be updated on the server
2. create your popupPanel outside of the first form and then use its own form:
Update
If you are using RichFaces 4 you can replace the limitToList attribute with limitRender
问题是弹出窗口不是 jsf 中表单的子级,您只需使用 domElementAttachment 属性来更改它。所以你的代码看起来像这样:
The problem is that the popup isn't a child of the form in jsf, you only need to use the domElementAttachment attribute to change that. So your code would look like this:
