Struts : Using Logic Iterate but not getting the updated list value in Action
I am developing a application which reads a XML , The values of these XML are set in a "Object" (consumerXML) and that object is set in a list and list will be set in session , Key being "results"
request.setAttribute("results", list)
The Flow is like this
- Welcome.JSP whose actionform is consumerxmlActionForm --> No Issues here
- editxml.jsp Even here the actionform is consumerxmlActionForm --> here list gets populated but doesnt pass the same, back.
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">
<head>
<title>Middleware UI</title>
<script language="JavaScript">
function submitFormEdit(frm,cmd) {
frm.operation.value = cmd;
frm.submit();
}
</script>
<html:base />
</head>
<body bgcolor="white">
<html:form action="/consumerxmlActionForm">
<html:hidden property="operation" />
<html:errors />
<table>
<tr>
<td align="center">beanID</td>
<td align="center">dayStartTime</td>
<td align="center">dayEndTime</td>
<td align="center">dayThreshold</td>
<td align="center">nightThreshold</td>
</tr>
<logic:iterate id="consumerXML" name="results" >
<tr>
<td align="center"><html:text name="consumerXML"
property="beanID" /></td>
<td align="center"><html:text name="consumerXML"
property="dayTime" /></td>
<td align="center"><html:text name="consumerXML"
property="nightTime" /></td>
<td align="center"><html:text name="consumerXML"
property="dayThreshold" /></td>
<td align="center"><html:text name="consumerXML"
property="nightThreshold" /></td>
</tr>
</logic:iterate>
<tr>
<td align="right"><html:submit onclick="submitFormEdit(consumerxmlActionForm, 'edit')">Change</html:submit></td>
</tr>
</table>
</html:form>
</body>

}
}
editxml.jsp displays the list properly, when I click on the "change" button I dont get the "results" in session. Is there any other way to fetch that list??
Thanks and Regards Raaghu.K
You should use the form to get values back to action and use the id and give VO there. Then Form will be available in action. You dont need session for this.
