I've solved the problem with help from people on expert exchange. For all who would benefit, here is what I did: Using a table wrapper I can create a dynamic link. In the method in the Wrapper that creates a dynamic link, I can access the database and get additional info to append to the dynamic URL. Note - table wrappers and column wrappers cannot exist on the same table - anything you want to have in a column wrapper will have to be put into the table wrapper or all sorts of ugly errors will appear. Here is what works for the Wrapper class: package teska.displaytag; /** * Licensed under the Artistic License; you may not use this file * except in compliance with the License. * You may obtain a copy of the License at * * http://displaytag.sourceforge.net/license.html * * THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR * IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED * WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE. * *Originally from: package org.displaytag.sample; * * */ import java.text.DecimalFormat; import java.util.*; //import org.displaytag.sample.*; import org.apache.commons.lang.time.FastDateFormat; import org.apache.commons.beanutils.*; import org.displaytag.decorator.TableDecorator; /** * This class is a decorator of the TestObjects that we keep in our List.
