public class ListDataSpecificPageTag
extends ListDataActionTag

Custom tag to generate hyperlink that can invoke instance of ListBrowserServlet and display a specific page. This class implements functionality similar to methods in listdata.js but only based on the data available at the time when the page is generated. If the page dynamically changes some of the list data pattern variables for example based on users' action, you should use methods in the listdata.js instead. Keep this functionality synchronized with the one provided by the JavaScript file.
