      com.tonbeller.wcf.scroller.ScrollerTag

All Implemented Interfaces:

javax.servlet.jsp.tagext.IterationTag, java.io.Serializable, javax.servlet.jsp.tagext.Tag

public class ScrollerTag

extends javax.servlet.jsp.tagext.TagSupport

Adds hidden fields to a form in a jsp that ensure that the browser keeps the scroll position when a user is navigating. This tag only works if the scroller.js javascript file is added to the page.

By default scrolling is disabled. A request handler should enable the scroller (@link com.tonbeller.wcf.scroller.Scroller) if its action requires keeping the scroll position
