Hi,
I followed the "struts-example/logon.jsp" to create some forms.
I also creates my "tlanForm", follows the example from "logonForm". However,
when the "tlanForm" fails the validation, it returns to the original page
with
"tlanForm" being re-created and resetted (I checked it from "servlet.log").
I could not figure it out. Did somebody has similar experience? I put the
"logon.jsp" in the same directory, and it works fine.
Here is some code snippet from "struts-config.xml"
===========================================
<action-mappings>
<!-- Process a tlan provisioning -->
<action path="/tlan"
type="com.VillageNetworks.tlan.TlanAction"
name="tlanForm"
scope="request"
input="/common/TLAN/provisioning.jsp" >
</action>
<!-- Process a user logon -->
<action path="/logon"
type="org.apache.struts.example.LogonAction"
name="logonForm"
scope="request"
input="/common/TLAN/logon.jsp">
</action>
===========================================
My "tlanForm" looks like this:
========================================
package com.VillageNetworks.tlan;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
