Java Struts：使用逻辑迭代，但不获取更新的列表值

我正在开发一个读取XML的应用程序，这些XML的值在对象consumerXML中设置，该对象在列表中设置，列表将在会话中设置，关键是结果

request.setAttribute("results", list)  

流程是这样的

Welcome.JSP，其actionform为consumerxmlActionForm->此处无问题 editxml.jsp即使在这里actionform是consumerxmlActionForm->here列表也会被填充，但不会返回相同的内容。 editxml.jsp：

jsp正确地显示了列表，当我单击“更改”按钮时，在会话中不会得到结果。有没有其他方法获取该列表

谢谢和问候

您应该使用表单获取返回操作的值，并使用id并在那里给出VO。然后表格将在行动中可用。你不需要这个课程

        <logic:iterate name="monthlyGainLossForm" property="ptcList" id="productTaxCat">

1你并不是在会议上要求什么，而是在请求中——我不确定这是问题中的输入错误还是代码错误。2无论哪种方式，如果要查找表单值，这些都是请求参数，应该在操作表单中。你是说你在提交表单后没有看到你期望的内容？重新提交表单后有问题吗？还有，你不应该使用
