you could use the org.apache.struts2.config_browser.ShowValidatorAction
then use java.beans.Introspector to acquire the bean from Validator.class
try
{
java.beans.BeanInfo beanInfoFrom =
java.beans.Introspector.getBeanInfo(validator.getClass(), Object.class);
}
catch (IntrospectionException e)
{
LOG.error("An error occurred", e);
addActionError("An error occurred while introspecting a validator of type " +
validator.getClass().getName());
return ERROR;
}
//make sure you get back non null validator from getSelectedValidator() accessor
public com.opensymphony.xwork2.validator.Validator
getSelectedValidator() {
return (com.opensymphony.xwork2.validator.Validator) validators.get(selected);
}

> i have a form that i display. but to display that form, i have to
> fetch some data from the database and then place that data on the
> valuestack (via backing beans). when the form is displayed, it expects
> that those backing beans should be populated. the form then posts to a
> save action.
>
> i have a <className>-<alias>-validation.xml that validates the form
> values. i have specified that if the result is "input" then go back to
> the form. the problem is that when the result is "input" and the
> form/page is reloaded, the beans are no longer populated and the form
> displays as blank.
>
> is there a way to intercept or is there a hook that i can grab to have
> an opportunity to populate my backing beans?
