jsf与Ajax的映射存在问题

Question

I have the following method in the manager which is called on blur of the patientId text field on a jsf page 我在管理器中有以下方法，该方法在jsf页面上的PatientId文本字段模糊时调用

private Patient patientData; //also have get and set 

public void search(ActionEvent actionEvent){
                 String aPatientId   = (String)getPatientInputTextField().getSubmittedValue();
                 Session s = null;
              try{
               s = HibernateUtil.getSession();
               StringBuffer sql =new StringBuffer("  from Patient p ");
               if(!(aPatientId == null || aPatientId.length() ==0 )){
                sql.append(where);
                sql.append(" p.pid=:patientId ");
                pidflag=true;
               }
               Query qList1 = s.createQuery(sql.toString());
               Integer patientId = aPatientId == null || aPatientId.length() == 0? 0 : Integer.valueOf(aPatientId);
               qList1.setInteger("patientId", patientId);
               int size = qList1.list().size();
               if(size > 0 ){
                 patientData = (Patient)qList1.list().get(0);
               }else if(size ==0 ){
                 System.err.println("NO MATCH FOUND");
                }
             }catch(Exception exception){
                 exception.printStackTrace();
             }
    }

I am having the following code in the JSF 我在JSF中有以下代码

<t:inputText id="patientId" binding="#{Manager.patientInputTextField}" 
        value="#{patient.pid}" readonly="#{readonly}">

<a4j:support event = "onblur" immediate="true"
         actionListener = "#{Manager.search}"  reRender = "firstName,lastName,phoneNum"/>
</t:inputText>
<t:inputText id='lastName'  value="#{patient.lastName}" />
<t:inputText id='firstName' value="#{patient.firstName}"/>
<t:inputText id='phoneNum'  value="#{patient.phoneNum}" />

when I check the patientData object in the managerI get the values of firstName,lastName & phonenumber without any issues the data is been returned by the manager 当我在管理器中检查PatientData对象时，我得到的名字，姓氏和电话号码的值没有任何问题，管理器返回了数据

The above JSP is an include Jsp (info.jsp) which is been included in the main.jsp 上面的JSP是包含在main.jsp中的include Jsp（info.jsp）

<f:view>
<h:messages ></h:messages>
<body>
<h:form id="headerinclude">
    <t:aliasBeansScope>
        <t:aliasBean alias="#{patient}" value="#{Manager.patientData}" />
          <f:subview id="billingView">
            <%@ include file="info.jsp"%>
          </f:subview>
    </t:aliasBeansScope>

Now I am not able to render the values for firstName, lastName and phoneNumber which is returned by the patientData object in the manager 现在，我无法呈现firstName，lastName和phoneNumber的值，这些值由manager中的PatientData对象返回

Any help / pointers in solving this would be appreciated trying to resolve this since a week now 自一周以来尝试解决此问题的任何帮助/指针将不胜感激

I was not doing the following in the Manager due to which the values were not setted in the JSP 由于没有在JSP中设置值，因此我没有在Manager中执行以下操作

patientInputTextField.setSubmittedValue(null); PatientInputTextField.setSubmittedValue（null）; patientFNameTextField.setSubmittedValue(null); PatientFNameTextField.setSubmittedValue（null）; patientLNameTextField.setSubmittedValue(null); PatientLNameTextField.setSubmittedValue（null）; patientPhoneNumTextField.setSubmittedValue(null); PatientPhoneNumTextField.setSubmittedValue（null）;
