PropertyNotFoundException导出数据表，其中列从backingbean方法获取文本

Question

我有一个primefaces数据表，并且使用以下代码也可以显示列值。

<c:forEach items="#{consolidatedReportByEquipmentBean.chairAmcDescList}"                            var="amcDescObj">
  <c:forEach items="#{consolidatedReportByEquipmentBean.chairPartsList}"
                                                            var="partsObj">
        <p:column style="text-align:center">
              <p:outputLabel value="#{consolidatedReportByEquipmentBean.parseTotalNoOfPartsChanged(chairPartsRepairedObj.chairServiceAutoId,amcDescObj.amcDescAutoId,partsObj.chairPartsAutoId)}"></p:outputLabel>
        </p:column>
</c:forEach>

当我点击数据表导出器时，会导致以下错误。

javax.el.PropertyNotFoundException:
/Admin/Reports/Consolidate/EquipmentServicedRecord.xhtml @279,184 value="#{consolidatedReportByEquipmentBean.parseTotalNoOfPartsChanged(chairPartsRepairedObj.chairServiceAutoId,amcDescObj.amcDescAutoId,partsObj.chairPartsAutoId)}": 
Property 'parseTotalNoOfPartsChanged' not found on type com.amcservicing.bean.ConsolidatedReportByEquipmentBean
