net.sourceforge.stripes.tag.WizardFieldsTag
public class WizardFieldsTag
Examines the request and include hidden fields for all parameters that have do not have form fields in the current form. Will include multiple values for parameters that have them. Excludes 'special' parameters like the source page parameter, and the parameter that conveyed the event name.
Very useful for implementing basic wizard flow without relying on session scoping of ActionBeans, and without having to name all the parameters that should be carried forward in the form.
