I've taken the Identify Features sample and modified it so that it only shows some of the attributes of the feature that's selected. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"                xmlns:s="library://ns.adobe.com/flex/spark"                xmlns:esri="http://www.esri.com/2008/ags"                pageTitle="Identify Features on the Map">     <!--     This sample shows how to identify features with a MapClick and the Identify task.         The IdentifyParameters designate which layers are being identified.     Identify operations can potentially return a lot of information     depending on the number of layers being identified and a given tolerance.     The tolerance is the number of pixels a feature is allowed to lie away     from the clicked point in order to be counted as a result.         In this sample, when user clicks the map, an "Identify" task is executed.         When the task finishes executing, the executeCompleteHandler function loops     through the features in the IdentifyResult and adds them to the map.     -->     <fx:Script>         <![CDATA[             import com.esri.ags.Graphic;

Hi Dan, I was able to replicate your problem, but then I changed the size of the BorderContainer to 550x500 and it acted normally.

Here are two ways of looking at it. If you want to add the attribute for LAND_AC6 only when none of the other fields have any attributes, then use this.
