Question

我正在研究从网络浏览器中提取电子邮件的j2ee6项目。我有一个命令Button，在用户输入电子邮件号码后调用提取方法。提取完成后，将显示确认拨号并显示提取的电子邮件数。这是我的xhtml代码：

<h:form id="mainform">
            <p:panel id="panelform" header="Email Extractor"  >        
                <h:panelGrid id="formulaire" columns="2">  
                    <h:panelGroup id="formblock" layout="block" >
                        <p:panelGrid columns="2">                                                     
                            <p:outputLabel for="Emailsnbr" value="Enter the emails'number:" />  
                            <p:inputText  id="Emailsnbr"   type="number"  requiredMessage="Emails number is required"
                                          value="#{mailMB.number}" required="true" label="Emailsnbr">    
                            </p:inputText> 
                        </p:panelGrid>
                    </h:panelGroup>
                </h:panelGrid> 
                <p:commandButton   value="Extract" style="width: 12%;height: 100%" update="tableemails, :confirmPurchase, :confirmPurchaseTest, :mainform" id="extractbutton" ajax="true" widgetVar="ButtonExtract"
                                   actionListener="#{mailMB.searchEmails()}" 
                                   icon="ui-icon-disk" styleClass="ui-priority-primary"
                                   onstart="blockUIWidget1.show();" oncomplete=" blockUIWidget1.hide(); if (args &amp;&amp; !args.validationFailed) freeMails();" />    

                <p:dialog widgetVar="blockUIWidget1" modal="true" closable="false"  >  
                    <h:panelGrid columns="2">                      
                        <p:graphicImage url="pictures/loading_bar.gif" width="264" height="34" alt="animated-loading-bar"/>
                        <h:outputText value="Please wait..." style="white-space: nowrap;"/>  
                    </h:panelGrid>  
                </p:dialog>
            </p:panel>  
        </h:form>  
   <p:confirmDialog closable="false" style="position: absolute;  width: 50px; border-color: blue" id="confirmPurchaseTest"  message="Your Database was successfully created. And contains #{mailMB.number} Emails "  
                         appendToBody="true"                                                             
                         header="Get Emails List" severity="info" widgetVar="emailsList"> 
            <h:form>        
                <p:commandButton id="getEmails" style="width: 30%;height: 100%" value="Get Emails" oncomplete="window.location.href = '/Hitonclick/emailsList.xhtml'"  >
                    <f:event type="preRenderView" listener="#{mailMB.preRender}"/>
                </p:commandButton>
                <p:commandButton id="declineTest" style="width: 30%;height: 100%" value="Decline" onclick="deleteDialog.show();" />       
            </h:form>

如果输入一个小数字，每件事情都可以。但是如果我为例600输入一个大数字，则提取时间变长（这个逻辑没有问题）并且确认对话框上显示的数字为0，尽管当我从数据库中检查它们时成功提取了电子邮件。它与ajax有什么关系？我怎样才能解决这个问题？

在确认对话框上显示输入值返回null
