Actually I can't find xwork 2.0.6, it's only 2.1 after 2.5 on the official
xwork site. I've downloaded strats 2.0.11.2 (i was using 2.0.11.1 before)
and tried it, but result is till the same.

Hi,
    I have this requirement to have a dynamic result dispatch. I am
accomplishing this the following way -
          <action name="MyAction_*" method="{1}"
               class="com.action.MyAction">
               <result name="success">${loginPage}</result>
               <result name="input">${loginPage}</result>
          </action>

    The page dynamically shows up, no problems there. However when
there's a validation error on this page, the framework returns a result
"input" and I guess its not able to find the value for ${loginPage} then.
My action class has the field loginPage with a getter method and thats how
it works for "success". What can I do to make the value of loginPage
available for result type "input" ?

Thanks,
Dwipin Chandran

I have a base domain with a currentPage property on it for this sort of
requirement. My action maintains this currentPage on the model which is
kept populated. Remember to set an initial value on the property in case
there are validation errors from the start.

Thanks for your reply, but is that the scenario when we use a model driven
action classes ?
I am directly using javabeans in my action class and have
actionClass-validation.xml for validations.
What do I do in such scenario?

Hello,

This has always been a problem. And a quick and decent way of solving this
is to forget OGNL and write your own implementation. Below listed the code
from AppFuse project which essentially creates a tag to expose all the
constants.

*package com.company.app.webapp.taglib;

import java.lang.reflect.AccessibleObject;
import java.lang.reflect.Field;
import java.util.HashMap;

import org.apache.commons.logging.LogFactory;
import com.loandukaan.app.Constants;


/**

* Libraries.</p>
*
* <p>It is designed to be used as follows:

* </p>
*
* <p>Optional values are "className" (fully qualified) and "scope".</p>
