Jsf primefaces 3.3.1数据表多选不起作用

我在应用程序中使用prime faces数据表，其中datatable中有一个复选框列用于选择某些行并将值发送到back bean，但它总是传递空值，有人能指出我的代码有什么问题吗

 <p:dataTable id="tblStatusSearch" var="item"
      selection="#{StatusAction.listBEeans}" 
        value="#{bondLocationStatusAction.listLocationEBeans}"
     rowKey="#{item.LocationId}">
         <p:column selectionMode="multiple"/>

选择

应指向数组而不是数组列表

---

尝试使

listBEean

成为这样的数组

private LocationEBean[] listBEeans;

看看橱窗

您的bean的范围是什么？那是@viewscope吗？你能把你的bean代码粘贴到这里吗？然后试试这个：

private List listBEeans=new ArrayList（）

@heidarzadeh，我已经编辑了我的bean，谢谢：）试着制作一个像这个私有位置ebean[]listBEeans这样的数组

listBEean

@Danial，谢谢你的建议，但是列表值仍然是空的，我遗漏了什么属性吗？不确定你的意思。。。。看看showcase（在我的回答中发布了链接）谢谢@Danial，它正在工作，我的服务器站点出现了一些问题。
