logic:present not validating as it was supposed to. where did i got it wrong ?

[Mel Cen]

regarding the problem ,

i cant get this piece of code to work.



<logic:present name="error" property="ErrorMessage">
Error: <bean:write name="error" property="ErrorMessage"/>
</logic:present>


If i am not mistaken, during the first time this page(Login.jsp) was load, this part of code will not be evaulated becoz error bean object is not present.

However, during submit, and i have debugged,

request.getSession().setAttribute("error", error);

gets executed and with mapping, the control was forwarded back to Login.jsp.

however, the code above was skipped again..

during object lookup, the object error is present but i am clueless on why it will not show the error?
==============================================================================

this are my tag lib(s)

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="Login" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

this is my ErrorClass class :

public class ErrorClass {

    private String ErrorMessage;

    public String getErrorMessage() {
        return ErrorMessage;
    }


    public void setErrorMessage(String aErrorMessage) {
        ErrorMessage = aErrorMessage;
    }
}

and this is my code

 public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        Util.ErrorClass error = new Util.ErrorClass();

        ActionForward result = mapping.findForward(FAIL);

        Login login = (Login) form;

        User user = new User();
        user.setUSERNAME(login.getUsername());
        user.setPASSWORD(login.getPassword());


        if (user.getUSERNAME().isEmpty() || user.getUSERNAME() == null) {
            error.setErrorMessage("You must supply a username");
        } else if (user.getPASSWORD().isEmpty() || user.getPASSWORD() == null) {
            error.setErrorMessage("You must supply a password");
        } else {
            UserManager um = new UserManager();
            boolean test = um.Login(user);

            if (test) {
                result = mapping.findForward(SUCCESS);

            } else {
                result = mapping.findForward(FAIL);

            }
        }
        if (error.getErrorMessage() != null) {
            request.getSession().setAttribute("error", error);

        }

        return result;
    }

Update : got it working with a little google seach..
