我在视图中有一个表单，该表单执行自动完成和gmap本地化的ajax部分处理。我的支持bean实例化了一个实体对象“
Address”，并向该对象引用了表单的输入：

@ManagedBean(name="mybean")
@SessionScoped
public class Mybean implements Serializable {
    private Address address;
    private String fullAddress;
    private String center = "0,0";
    ....

    public mybean() {
        address = new Address();
    }
    ...
   public void handleAddressChange() {
      String c = "";
      c = (address.getAddressLine1() != null) { c += address.getAddressLine1(); }
      c = (address.getAddressLine2() != null) { c += ", " + address.getAddressLine2(); }
      c = (address.getCity() != null) { c += ", " + address.getCity(); }
      c = (address.getState() != null) { c += ", " + address.getState(); }
      fullAddress = c;
      addMessage(new FacesMessage(FacesMessage.SEVERITY_INFO, "Full Address", fullAddress));
      try {
            geocodeAddress(fullAddress);
        } catch (MalformedURLException ex) {
            Logger.getLogger(Mybean.class.getName()).log(Level.SEVERE, null, ex);
        } catch (UnsupportedEncodingException ex) {
            Logger.getLogger(Mybean.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
            Logger.getLogger(Mybean.class.getName()).log(Level.SEVERE, null, ex);
        } catch (ParserConfigurationException ex) {
            Logger.getLogger(Mybean.class.getName()).log(Level.SEVERE, null, ex);
        } catch (SAXException ex) {
            Logger.getLogger(Mybean.class.getName()).log(Level.SEVERE, null, ex);
        } catch (XPathExpressionException ex) {
            Logger.getLogger(Mybean.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    private void geocodeAddress(String address)
            throws MalformedURLException, UnsupportedEncodingException,
            IOException, ParserConfigurationException, SAXException,
            XPathExpressionException {

        // prepare a URL to the geocoder
        address = Normalizer.normalize(address, Normalizer.Form.NFD);
        address = address.replaceAll("[^\\p{ASCII}]", "");

        URL url = new URL(GEOCODER_REQUEST_PREFIX_FOR_XML + "?address="
                + URLEncoder.encode(address, "UTF-8") + "&sensor=false");

        // prepare an HTTP connection to the geocoder
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        Document geocoderResultDocument = null;

        try {
            // open the connection and get results as InputSource.
            conn.connect();
            InputSource geocoderResultInputSource = new InputSource(conn.getInputStream());

            // read result and parse into XML Document
            geocoderResultDocument = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(geocoderResultInputSource);
        } finally {
            conn.disconnect();
        }

        // prepare XPath
        XPath xpath = XPathFactory.newInstance().newXPath();

        // extract the result
        NodeList resultNodeList = null;

        // c) extract the coordinates of the first result
        resultNodeList = (NodeList) xpath.evaluate(
                "/GeocodeResponse/result[1]/geometry/location/*",
                geocoderResultDocument, XPathConstants.NODESET);
        String lat = "";
        String lng = "";
        for (int i = 0; i < resultNodeList.getLength(); ++i) {
            Node node = resultNodeList.item(i);
            if ("lat".equals(node.getNodeName())) {
                lat = node.getTextContent();
            }
            if ("lng".equals(node.getNodeName())) {
                lng = node.getTextContent();
            }
        }
        center = lat + "," + lng;
    }

自动补全和map
ajax请求可以正常工作，然后再提交时处理整个表单。如果验证失败，则即使无法在视图中更新fullAddress字段（即使在ajax请求之后在备用bean上正确设置了其值），ajax仍然可以正常工作。

<h:outputLabel for="address1" value="#{label.addressLine1}"/>
<p:inputText required="true" id="address1" 
          value="#{mybean.address.addressLine1}">
  <p:ajax update="latLng,fullAddress" 
          listener="#{mybean.handleAddressChange}" 
          process="@this"/>
</p:inputText>
<p:message for="address1"/>

<h:outputLabel for="address2" value="#{label.addressLine2}"/>
<p:inputText id="address2" 
          value="#{mybean.address.addressLine2}" 
          label="#{label.addressLine2}">
  <f:validateBean disabled="#{true}" />
  <p:ajax update="latLng,fullAddress" 
          listener="#{mybean.handleAddressChange}" 
          process="address1,@this"/>
</p:inputText>
<p:message for="address2"/>

<h:outputLabel for="city" value="#{label.city}"/>
<p:inputText required="true" 
          id="city" value="#{mybean.address.city}" 
          label="#{label.city}">
  <p:ajax update="latLng,fullAddress" 
          listener="#{mybean.handleAddressChange}" 
          process="address1,address2,@this"/>
</p:inputText>
<p:message for="city"/>

<h:outputLabel for="state" value="#{label.state}"/>
<p:autoComplete id="state" value="#{mybean.address.state}" 
          completeMethod="#{mybean.completeState}" 
          selectListener="#{mybean.handleStateSelect}"
          onSelectUpdate="latLng,fullAddress,growl" 
          required="true">
  <p:ajax process="address1,address2,city,@this"/>
</p:autoComplete>
<p:message for="state"/>

<h:outputLabel for="fullAddress" value="#{label.fullAddress}"/>
<p:inputText id="fullAddress" value="#{mybean.fullAddress}" 
          style="width: 300px;"
          label="#{label.fullAddress}"/>
<p:commandButton value="#{label.locate}" process="@this,fullAddress"
          update="growl,latLng" 
          actionListener="#{mybean.findOnMap}" 
          id="findOnMap"/>

<p:gmap id="latLng" center="#{mybean.center}" zoom="18" 
          type="ROADMAP" 
          style="width:600px;height:400px;margin-bottom:10px;" 
          model="#{mybean.mapModel}" 
          onPointClick="handlePointClick(event);" 
          pointSelectListener="#{mybean.onPointSelect}" 
          onPointSelectUpdate="growl" 
          draggable="true" 
          markerDragListener="#{mybean.onMarkerDrag}" 
          onMarkerDragUpdate="growl" widgetVar="map"/>
<p:commandButton id="register" value="#{label.register}" 
          action="#{mybean.register}" ajax="false"/>

如果刷新页面，验证错误消息就会消失，并且ajax会按预期完成fullAddress字段。

验证期间还会发生另一种怪异的行为：如代码所示，我已禁用了表单字段的bean验证。在发现其他验证错误之前，此工作正常进行，然后，如果我重新提交表单，JSF将对该字段进行bean验证！

我想我在验证状态中遗漏了一些东西，但是我无法弄清楚它出了什么问题。有谁知道如何调试JSF生命周期？有任何想法吗？
