Struts：使用邏輯迭代但沒有獲取更新列表值在操作

我正在開發一個讀取XML的應用程序，這些XML的值在「對象」（consumerXML）中設置，並且該對象設置在列表中和名單將在會議上進行設置，鍵爲「結果」Struts：使用邏輯迭代但沒有獲取更新列表值在操作

request.setAttribute("results", list)

流程是這樣的

的welcome.jsp它的ActionForm consumerxmlActionForm - >這裏沒有問題
editxml.jsp即使在這裏，actionform是consumerxmlActio nForm - >這裏列表被填充，但不通過相同的，回來。

editxml.jsp：

<%@ taglib uri="/tags/struts-bean" prefix="bean"%> 
<%@ taglib uri="/tags/struts-html" prefix="html"%> 
<%@ taglib uri="/tags/struts-logic" prefix="logic"%> 


<html:html locale="true">

<title>Middleware UI</title> 
<script language="JavaScript">

frm.operation.value = cmd; 
frm.submit(); 
}

editxml.jsp正確顯示的列表中，當我點擊「更改」按鈕，我不明白的「結果」在會議中。有沒有其他的方式來獲取該列表？

1）您不是要求會話中的任何內容，而是來自請求 - 我不確定這是問題中的拼寫錯誤還是代碼。 2）無論哪種方式，如果你正在尋找表單值，那些是請求參數，並且應該在動作表單中。你是否說在提交後你沒有看到你期望的形式？ –

重新提交表單後是否有問題？ – Naved

另外，你不應該使用 Panos

你應該用表格來獲取值回操作，然後使用ID，並給VO那裏。然後表格將可用。你不需要這個會話。

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