< H:形式> within< ui:repeat>不完全工作,只有最后< h:form>被处理 [英] <h:form> within <ui:repeat> not entirely working, only the last <h:form> is processed
问题描述
我想编辑同一页面中的项目列表。每个项目都应该使用单独的表格进行编辑。我在ui中创建一个h:form:重复。只有当最后一个表单被提交时,用户输入才会被应用到托管bean。对于所有其他形式,用户输入不适用于模型。
@ManagedBean
公共类控制器{
Logger logger = Logger.getLogger(TestWeb);
私人列表< Customer> customerList;
公共列表< Customer> getCustomerList(){
if(customerList == null){
customerList = new ArrayList< Customer>();
customerList.add(新客户(Daffy Duck,daffy@example.com));
customerList.add(新客户(Bugs Bunny,bugs@example.com));
customerList.add(新客户(Samity Sam,sam@example.com));
}
返回customerList;
public String updateCustomer(Customer c){
logger.info(Updating:+ c.getName());
返回null;
$ / code $ / pre
在视图中我有$ / $>
< ui:repeat var =cvalue =#{controller.customerList}>
< h:form>
< h3>编辑客户< / h3>
名称:< h:inputText value =#{c.name}/>< br />
电子邮件:< h:inputText value =#{c.email}/>< br />
< h:commandButton value =Update
action =#{controller.updateCustomer(c)}/>
< / h:表格>
< / ui:repeat>
我在没有任何解决方案的情况下搜索小时。什么才是正确的方法来做到这一点?我可以通过使用单个表单并使用ui进行破解:在其中重复。但是有很多问题,我宁愿不采取这样的路线。感谢。
解决方案这是状态保存< ui:repeat>
在莫哈拉。在 http://java.net/jira/browse/JAVASERVERFACES 上有几个类似的问题报告,其中 issue 2243 。
基本上有两个选项:使用另一个迭代组件(例如< c:forEach>
,< h:dataTable>
,< ; t:dataList>
,< p:dataList>
等),或者用MyFaces替换Mojarra(< ; ui:repeat>
在这个构造中可以正常工作)。
I will like to edit a list of items in the same page. Each item should be edited using a separate form. I am creating a h:form within ui:repeat. Only when the last form is submitted, the user input is applied to the managed bean. For all other forms, user input is not applied to the model.
@ManagedBean
public class Controller {
Logger logger = Logger.getLogger("TestWeb");
private List<Customer> customerList;
public List<Customer> getCustomerList() {
if (customerList == null) {
customerList = new ArrayList<Customer>();
customerList.add(new Customer("Daffy Duck", "daffy@example.com"));
customerList.add(new Customer("Bugs Bunny", "bugs@example.com"));
customerList.add(new Customer("Samity Sam", "sam@example.com"));
}
return customerList;
}
public String updateCustomer(Customer c) {
logger.info("Updating: " + c.getName());
return null;
}
}
In the view, I have
<ui:repeat var="c" value="#{controller.customerList}">
<h:form>
<h3>Edit Customer</h3>
Name: <h:inputText value="#{c.name}"/><br/>
E-mail: <h:inputText value="#{c.email}"/><br/>
<h:commandButton value="Update"
action="#{controller.updateCustomer(c)}"/>
</h:form>
</ui:repeat>
I search for hours without any solution. What will be the correct way to do this? I can hack it by using a single form and using a ui:repeat within it. But there are many issues with that and I will rather not take that route. Thanks.
解决方案 This is a bug in state saving of <ui:repeat>
in Mojarra. There are several similar issue reports at http://java.net/jira/browse/JAVASERVERFACES, among others issue 2243.
You have basically 2 options: use another iterating component (e.g. <c:forEach>
, <h:dataTable>
, <t:dataList>
, <p:dataList>
, etc), or replace Mojarra by MyFaces (the <ui:repeat>
in this construct works properly in there).
