Subject: Struts - JSP does not store the user entered values when i
click back
Good Morning,
When I load the jsp, go to next page and click on browser back button.
User entered values are not stored.
This happens everytime I open a new browser and launch the jsp page,
happens only for the first submit, does not happen otherwise.
Any ideas? Thanks in advance.
Below is the jsp and the action class :
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %> <html:html
locale="true">
<head>
<title><bean:message key="login.title"/></title>
<html:base/>
</head>
<body bgcolor="white">
<html:errors/>
<table border="1" size="100%">
<tbody>
<tr>
<bean:message key="login.title"/>
</tr>
<html:form action="/jsp/login" focus="username">
<tr>
<td><bean:message key="login.username"/></td>
<td><html:text property="username" size="16"
maxlength="16"/></td>
</tr>
<tr>
<td><bean:message key="login.password"/></td>
<td><html:password property="password" size="16"
maxlength="16" redisplay="false"/></td>
</tr>
<tr>
<td align="right"><html:submit property="submit"
value="Submit"/></td>
<td align="left"><html:reset/></td>
</tr>
</html:form>
</tbody>
</table>
</body>
</html>
