[displaytag-user] TableDecorator question with 1.1 upgrade

[Tom <dis...@ea...>]

Displaytag 1.0 has been working great for us but we finally decided to
upgrade to 1.1 to take advantage of external sorting. However, after
following the steps listed here:
http://displaytag.sourceforge.net/11/migrating.html
the decorating that happens in our TableDecorators does not appear on
the rendered page. Strangely if I examine the rows in a debugger, they
are clearly being modified in the TableDecorator - it just doesn't get
displayed on the page. Any ideas what I am doing wrong?
I'll attach some example code below that functions fine for us in 1.0
but not in 1.1

Thanks in advance,
Tom

import org.displaytag.decorator.TableDecorator;
import java.util.LinkedHashMap;

public class DrillDownTableDecorator extends TableDecorator {
	private int rowCounter = 0;

	public String startRow() {
		rowCounter++;
		LinkedHashMap map = (LinkedHashMap) getCurrentRowObject();
		Integer rowNumOffset = (Integer) map.get("rowNumOffset");
		if (rowNumOffset == null) {
			rowNumOffset = new Integer(0);
		}
		map.put("rowNum", String.valueOf(rowCounter +
rowNumOffset.intValue()));
		return "";
	}

	public void finish() {
		rowCounter = 1;
	}
}
