Question

当我提交jsf页面的表单并重定向到另一个页面时，就会发生这种情况

<p:outputPanel id="panelx" >

        <form method="post" action="https://someUrl/payment/response" id="xForm" name="xForm">

        <input name="id" type="hidden" id="id" size="50" maxlength="10" 
        value="#{somevalue}" />     

    <input type="submit" id="btnsubmit" value="submit" style="display: none" />
</form>
    </p:outputPanel>

但是当我在jsp页面下方使用jsp页面及其中的相同表单时，我可以解决此问题

<body onload="document.paymentRedirect.submit()">

 <form method="post" name="paymentRedirect" id="paymentRedirect"  action="https://someUrl/payment/response">

      <input id="id" name="id" class="x25" size="40" type="hidden" 
      value="<% out.print(request.getParameter("id"));%>">
 
 </form>

</body>

以下完整的堆栈跟踪信息，我无法理解正在发生什么。任何帮助将不胜感激
