Hi there! [Windows NT, VAJ 3.5.3 WTE]
I'm trying to use the approach from the "struts-example" application to edit
and save a form. The user is directed to "editInfo.do" which populates the
form and forwards to "editinfo.jsp" which, on submit (starting a new
request?), invokes the "saveInfo.do". But when I enter the perform method of
the Action object associated with the "saveInfo" mapping a new form has been
created and I can no longer access the values from the editInfo form. I can
see that it hasn't merely been cleared (ActionForm.reset(...)) because I
dump it to stdout.
I brutally 'clipboarded' the code from the struts-example app (see bottom of
message) so I'm having a really really hard time trying to understand why it
wont work! If you could offer any advice I would be extremely grateful.

[struts-config.xml]
<!-- Edit info -->
<action
path="/editInfo"
type="myinfo.EditInfoAction"
name="infoForm"
scope="request"
validate="false">
<forward name="success" path="/editinfo.jsp" />
</action>
<!-- Save info -->
<action
path="/saveInfo"
type="myinfo.SaveInfoAction"
name="infoForm"
scope="request"
input="/editinfo.jsp"
validate="true">
<forward name="success" path="/editInfo.do"/>
</action>
[/struts-config.xml]
[EditInfoAction.perform()]
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// Extract attributes we will need
Locale locale = getLocale(request);
MessageResources messages = getResources();
HttpSession session = request.getSession();
// retreive the form or create a new one if it isn't there >>
if (form == null) {
if (servlet.getDebug() >= 1)
servlet.log(" Creating new EditInfoForm bean under key " +
mapping.getAttribute());
form = new EditInfoForm();
if ("request".equals(mapping.getScope()))
request.setAttribute(mapping.getAttribute(), form);
else
session.setAttribute(mapping.getAttribute(), form);
}
// FORM IS POPULATED HERE
System.out.println(form);
// Forward control to the specified success URI
return (mapping.findForward("success"));
}
[/EditInfoAction.perform()]
[SaveInfoAction.perform()]
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// Extract attributes we will need
Locale locale = getLocale(request);
MessageResources messages = getResources();
EditInfoForm infoForm = (EditInfoForm)form; // <-- NEWLY CREATED
FORM :(
// TODO: Update personal info >>
System.out.println("SaveInfoAction.perform(): Updating info:");
System.out.println("\t" + infoForm);
// Forward control to the specified success URI
return (mapping.findForward("success"));
}
[/SaveInfoAction.perform()]
Ofcourse there's alot more to the jsp file than shown here but for clarity's
sake:
[editinfo.jsp]
<html:form action="/saveInfo">
<!-- [properties deleted] -->
<html:submit><bean:message key="editinfo.button.update"/></html:submit>
</html:form>
[/editinfo.jsp]
