我有一个Facelets视图如下:

<h:form id="f1">
<p:panelGrid id="p1" columns="2"> 
<p: inputText value="Distance Travelled::/><p:inputText value="#{airTransportUsage.distance}" immediate="true"
required="true" requiredMessage="Distance Travelled Field cannot be left blank.."
converterMessage="Distance Travelled must be a number"
validatorMessage="Distance Travelled must be a valid number.."
id="dis">
<f:validateLongRange minimum="1"/>
</p:inputText>
<p:commandButton value="Reset" action="#{airTransportUsage.reset}" update=":f1:p1" />
</p:panelGrid>
</h:form>

单击重置按钮时,由于验证,永远不会执行相应的方法.我无法使用immediate="true"我的重置按钮,因为它会产生一些其他问题.

这是我的注销方法:

public String logout() throws IOException, ServletException 
{
    FacesContext context = FacesContext.getCurrentInstance();
    ExternalContext ec = context.getExternalContext();
    HttpSession session = (HttpSession) ec.getSession(false);
    HttpServletResponse response = (HttpServletResponse) ec.getResponse();
    final HttpServletRequest request = (HttpServletRequest)ec.getRequest();
    session.invalidate();
    Cookie[] cookies = request.getCookies();  
    Cookie opentoken = null;  
    for(Cookie c : cookies){  
        if (c.getName().equals("opentoken")){ 
            if (session != null){  
            opentoken = c;  
            opentoken.setMaxAge(0);  
            opentoken.setValue("");  
            response.addCookie(opentoken);
            response.sendRedirect(request.getContextPath()); 
            response.setHeader("Pragma", "no-cache"); 
            response.setHeader("Cache-Control", "no-cache"); 
            response.setHeader("Cache-Control", "no-store"); 
            response.setHeader("Cache-Control", "must-revalidate"); 
            response.setHeader("Expires", "Mon, 8 Aug 2006 10:00:00 GMT");//past date 
            }
            break;  
        }
    }
    context.getExternalContext().getSessionMap().remove("#{LogoutBean}");
    return "login.xhtml?faces-redirect=false"; …

我有一个代码如下:

 <p:commandButton value="#{actualProductionEntry.val}" onclick="confirmation.show()"/>
 <p:confirmDialog id="confirmDialog" message="Are you sure?" header="Confirm Submission"                                 severity="alert" widgetVar="confirmation">         
     <p:commandButton id="confirm" value="Yes" oncomplete="confirmation.hide()" action="#   {actualProductionEntry.insert(login.userid,login.uid,login.dname,login.rptid)}"   update=":df:data :f1:p2 :dp:app"/>  
     <p:commandButton id="decline" value="No" onclick="confirmation.hide()" type="button" />                 
 </p:confirmDialog> 

现在,如何在确认之前进行验证而不影响我的bean？
