Jsf 如何知道数据表是否在Primefaces 5中过滤

最近，我从JSF2.0迁移到JSF2.2，从Primefaces 3.5迁移到Primefaces 5

我有一个表，每列都有过滤器。使用primefaces 3.5进行过滤效果良好

但在Primefaces中，我看到当Primefaces 3.5返回就绪过滤列表时，getFilteredValue（）返回null

有什么问题？以及如何检查数据表是否显示服务器端已过滤的数据？

我同样的事情也发生在从3.5版移动到4.0版的过程中。 我使用remotecomand调用actionlistener方法解决了这个问题

在PF 5.0中，您需要明确定义

filteredValue

：

<p:dataTable  id="gwsReportAllPartListDataTable" 
  value="#{viewAllAnalyticsBean.gwsReportPartTwoList}" 
  var="report" 
  paginator="true" 
  rows="100"
  paginatorTemplate="{PageLinks} {CurrentPageReport}" 
  currentPageReportTemplate="{currentPage} #{dictionary['out_of']} {totalPages}" 
  emptyMessage="#{dictionary['nothing_is_here']}" 
  scrollable="true"
  scrollWidth="1221"
  scrollHeight="500"
