public class ERXDataHyperlink
extends ERXHyperlink

ERXDataHyperlink works like a WOHyperlink except that instead of turning unknown bindings into tag attributes, it instead passes them to the page specified in pageName. For instance, if you have a pageName = "PersonPage" and person = "$currentPerson", when the link is clicked, the next page will be a PersonPage with setPerson(currentPerson) passed into it. You can pass in as many bindings as you need, but there are some bindings that are used by this element by itself and thus are not passed to the page: The ones defined by WOHyperlink and additionally "id", "class", "onclick" and "otherTagString", which are handled like bindings on a stock WOHyperlink. If the "pageName" binding is not set, ERXDataHyperlink will behave like a regular WOHyperlink.
