dear all
in JSP file i have
<s:select label="mainCategory" name="mainCategory"
    list="mainCategory" listKey="id" listValue="name"
value="%{mainCategory.{id}}" required="true" />
in struts.xml file i have
<action name="add" class="com.baibai.action.C0032_AddAction">
<result name="success">/C0031_List.jsp</result>
<result name="input">/C0032_Add.jsp</result>
</action>
in Java file i have
public List<DropDownList> getMainCategory() {
List<DropDownList> ls = null;
DropDownList dr = null;
dr.setId(0);
dr.setName("--please select one of these--");
ls.add(dr);
return ls;
}
but the error appear
tag 'select', field 'list', name 'mainCategory': The requested list key
'mainCategory' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]

Hi,

Is there any key architectural changes between 2.0.14 and 2.1.8? Or does
the key concepts remain the same?

Thanks,
Jayson

Hi Jayson,

I have upgraded version of struts for my project (from 2.0.14 to 2.1.8), and
for my personal experience I think that key concepts and base architecture
aspects are the same. For my experience version 2.1.8 is more stable, better
performance (first observations from users) ...

Into update there are a troubles, only if you use dojo intensely into your
application, because dojo plugin is deprecated and not supported for future
versions (infact dojo plugin is a wrapper of an old version dojo toolkit). I
have decided to remove referance to dojo plugin and use directly dojo
toolkit.

You can have information on differences between the versions at

http://struts.apache.org/2.1.8.1/docs/migration-guide.html

I have the same serious problem that is similar to an old thread
http://marc.info/?l=struts-user&m=121234554714110&w=2
 
I use session object to manage user data for my company's e-commerce site, from time to time,specially when have high web access traffic, the session data could overlap, and from different user object. It is very frustrated, because it not happen always, but once a while, but serious problem, i do not know it is bug for strusts or not.
 
public ActionForward execute(ActionMapping mapping,
                               ActionForm form,
                               HttpServletRequest request,
                               HttpServletResponse response
                               ) throws Exception
{
HttpSession session=request.getSession();
UserInfoForm uif, t_uif;
Boolean check_cookie=false;
String login=null;
if (session==null) {
        session=request.getSession(true);
        check_cookie=true;
   }
else {
          uif=(UserInfoForm) session.getAttribute(BeanNames.USERINFO);
          if (uif==null || uif.getLogin_id()==null ||uif.getLogin_id().equals("Visit") )       
             check_cookie=true;
         }
 
if (check_cookie) {
        t_uif=new UserInfoForm();
        uif.setLogin_id("Visit");
        session.setAttribute(BeanNames.USERINFO,uif);
        Cookie theCookie=null;uif.setLogin_id("Visit");
        Cookie cookieList[]=request.getCookies();
        if (cookieList!=null) {
           for (int i=0; i<cookieList.length;i++) {
               theCookie=cookieList[i];
               if ( theCookie.getName().equals("XXX") )           /* XXX=company name */
                  login=theCookie.getValue();
               }
           if (login==null)
             t_uif=null;
           else
             t_uif=security_service.ask(login);      /* to access db, to verify user info ...*/
           if (t_uif==null)
              t_uif.setLogin_id("Visit");
           session.setAttribute(BeanNames.USERINFO,t_uif);
           }
    }
 
uif=(UserInfoForm) session.getAttribute(BeanNames.USERINFO);
 
.....
 
average once a month or when have heavy web traffic, the 'USERINFO' session object could be overlap with wrong customer info.
 
please give me any clue, tks in advance

yeah..the problem starts here
http://www.docjar.com/html/api/sun/reflect/DelegatingMethodAccessorImpl.java.html
 30  /** Delegates its invocation to another MethodAccessorImpl and can
 31     change its delegate at run time. */
 32  
 33  class DelegatingMethodAccessorImpl extends MethodAccessorImpl {
 34     private MethodAccessorImpl delegate;
 35  
 36     DelegatingMethodAccessorImpl(MethodAccessorImpl delegate) {
 37       setDelegate(delegate);
 38     }
 39  
 40     public Object invoke(Object obj, Object[] args)
 41       throws IllegalArgumentException, InvocationTargetException
 42     {
 43       return delegate.invoke(obj, args);
 44     }
either the MethodAccessorImpl delegate is incorrect
or the method is 'inaccessible' or is incorrect

to verify method if you have the context try this testcase from com.opensymphony.xwork2.util.reflection.ReflectionContext.java

  public static boolean isDenyMethodExecution(Map<String, Object> context) {
    return getBooleanProperty(ReflectionContextState.DENY_METHOD_EXECUTION, context);
  }

a simpler testcase would be
<%
try
{commentInTag.getClass().getMethod("isUserSubscribedViaEmail",currentUserInTag.getClass());
}
catch(NoSuchMethodException nsme)
{
System.err.println("NoSuchMethodException produced message = "+nsme.getMessage());
}
catch(SecurityException sec_exp)
{
System.err.println("SecurityException produced message "+sec_exp.getMessage());
}
%>
