It is working! For future generations, here is what I did:
* Created a custom class that extends ListItemRenderer. * Overrode createChildren, measure, commitProperties, and updateDisplayList as Alex described, calling super on each. The only glitch here is I had to set label.visible == false in UDL because the label is duplicating one of the fields I am setting. Also, to get measuredHeight in measure(), I had to do getExplicitOrMeasuredHeight () on my textfield. When I set measuredHeight based on the textfield.height, all the rows were the same height, about 50-75 px. * No get or set data() or listData() in my new class. No other methods at all actually, except the ones listed above. The long national nightmare is over! Many thanks Alex and Tracy for your patient and informative replies.
