请帮助我。我试图在1个JSP上使用2个表单。第一个表单工作得很好。当我尝试提交第二个表单时，我得到IllegalStateException。我已经阅读了很多关于这个问题的内容，但是没有任何东西可以解决我目前的问题。BindingResult和bean名称的普通目标对象都不作为请求属性（Spring MVC）
形式：
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<head>
<%@ include file="../views/common/imports.jsp" %>
<title>MARC</title>
</head>
<body onload="togglePieLines()">
<%@ include file="../views/common/header.jsp"%>

完整堆栈跟踪： 
有时堆栈跟踪更改为： 
这是有点儿奇怪，因为我应该在提交和我不知道为什么第一个表格有问题
您可以提供完整的堆栈跟踪？ – 2015-02-10 13:13:19
只需一秒钟。我将上传完整的堆栈跟踪 – 2015-02-10 13:16:30
