最近，我已经从JSF 2.0迁移到JSF 2.2和Primefaces 3.5到Primefaces 5
我有一张表，每列都有过滤器。使用primefaces 3.5
进行过滤效果很好<p:dataTable id="gwsReportAllPartListDataTable"

我有onFilterDataTable函数，每次用户开始输入时都会触发，以过滤每列上的字段。
public void onFilterDataTable(AjaxBehaviorEvent event) {
System.out.println("Filter called");
DataTable table = (DataTable) event.getSource();
filteredGwsReportPartTwoList = table.getFilteredValue();
isFiltered = filteredGwsReportPartTwoList.size() != gwsReportPartTwoList.size();
countTotalsAndGenerateGwsReportPartOne(isFiltered);
}
但在Primefaces中显示，当Primefaces 3.5返回准备好的过滤列表时，getFilteredValue（）返回null。
有什么问题？以及如何检查数据表是否在服务器端显示已过滤的数据？

我发生了从3.5版到4.0版的事情。 我使用remotecomand解决了问题，调用了actionlistener方法。
<p:dataTable filterDelay="1000" emptyMessage="No se encontraron elementos" widgetVar="tb1"
id="tablaFact" var="item" selection="#{listadoFacturasMB.selectedFactura}" selectionMode="single" paginator="true"
rows="20" rowKey="#{item.idFactura}" value="#{listadoFacturasMB.facturaUtilList}" filteredValue="#{listadoFacturasMB.filterFacturaUtilList}">
<p:ajax event="filter" oncomplete="handleLoadStart();" update=":frm1:tablaFact :frm1:panelTotal"/>
<p:column style="width:10%" headerText="Importe Total" id="cff3">
<h:outputText value="#{item.importeTotal}"/>
</p:column>
<p:column style="width:10%" headerText="Importe CUC" id="cjj3">
<h:outputText value="#{item.importeCuc}"/>
</p:column>
</p:dataTable>
<p:remoteCommand id="rcom" name="loadRemoteContent" process="@this" update="panelTotal, tablaFact"
actionListener="#{listadoFacturasMB.filterListener2}"/>
Backingbean
public void filterListener2() {
try {
if (filterFacturaUtilList != null) {
//your code
}
}
} catch (Exception e) {
JsfUtil.addErrorMessage(e, "Error: filterListener() " + e.getMessage());
}
}

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"
filteredValue="#{someBeanOrScope.someList}">
