我在primefaces 5.0上使用datatable的filterFunction方法.我想按列标题上的日期范围过滤生日.

在浏览器控制台上,我收到此错误:

<?xml version="1.0"
   encoding="utf-8"?><partial-response><error><error-name>java.lang.ClassCastException</error-name><error-message><![CDATA[javax.faces.component.UIPanel
   cannot be cast to
   javax.faces.component.ValueHolder]]></error-message></error></partial-response>

数据表:

 <p:dataTable var="person" value="#{testDateRange.persons}"
              id="personTable" paginator="true" styleClass="customTableStyle" editable="true"
              rows="10"  resizableColumns="true"
              emptyMessage="No persons"
              filteredValue="#{testDateRange.filteredPersons}"
              widgetVar="dateRangeWidget" >

     <p:column id="nameId" filterBy="name" sortBy="name" filterMatchMode="contains" headerText="Name">
         <h:outputText value="#{person.name}" />
     </p:column>

     <p:column id="birthdayId" headerText="birthday" filterBy="birthday" filterFunction="#{testDateRange.filterByDate}">
         <f:facet name="filter">
             <p:calendar id="from" value="#{testDateRange.dateFrom}"   styleClass="customCalendar" pattern="dd/MM/yyyy">
                 <p:ajax event="dateSelect" oncomplete="PF('dateRangeWidget').filter()" update="personTable"/>
             </p:calendar>
             <p:calendar id="to" value="#{testDateRange.dateTo}" styleClass="customCalendar" pattern="dd/MM/yyyy">
                 <p:ajax event="dateSelect" oncomplete="PF('dateRangeWidget').filter()" update="personTable"/>
             </p:calendar>
         </f:facet>
         <h:outputText value="#{person.birthday}"  >
             <f:convertDateTime pattern="dd/MM/yyyy"/>
         </h:outputText>
     </p:column>
 </p:dataTable>

豆:

@Component("testDateRange")
@Scope("session")
public class TestDateRangeBean {

    private …

我有一个通过xml-rpc发送字典的简单示例:

 class CTest(object):
    def __init__(self):
        self.node1 = {'data':'zek', 'parent':{},  'children':[]}
        self.node2 = {'data':'bill', 'parent':{}, 'children':[]}
        self.node1['children'].append(self.node2)
        self.node2['parent'] = self.node1

    def getNode(self):
        return self.node1

我有两个字典:node2是node1的子节点,同时node2将node1的引用作为父变量.所以它是一个递归字典.当我尝试通过XML-RPC发送node1时,我得到了以下异常:

#Command to execute xml-rpc dump method for serialization
test = CTest()
xmlrpclib.dumps((test,), 'Node Object')
#Exception
raise TypeError, "cannot marshal recursive dictionaries"

是否可以通过XML-RPC发送node1(不更改字典结构)？

谢谢.
