    DataGrid having a dataField as an AS object

      I have a DataGrid with a dataProvider of an ArrayCollection of these objects:

      package uiowa.dpte.biz
      public class AlternativeToAttribute
      public var id:int;
      public var rating:Number;
      public var currentAlternative:uiowa.dpte.biz.Alternative;
      public var currentAttribute:uiowa.dpte.biz.Attribute;

      The Attribute object:

      package uiowa.dpte.biz
      import mx.collections.ArrayCollection;

      public class Attribute
      public var attributeId:int;
      public var alternativeToAttributes:ArrayCollection;
      public var name:String;

      Everything loads fine except the currentAttribute.name for one of the DataGridColumn dataFields.

      <mx:DataGrid width="432" height="150" dataProvider="{alternativesToAttributes}"
      id="dgAltToAtr" editable="true" mouseDown="Alert.show(dgAltToAtr.selectedItem.currentAttribute.name)">
      <mx:DataGridColumn headerText="id" dataField="id" editable="false"/>
      <mx:DataGridColumn headerText="rating" dataField="rating" editable="true"/>
      <mx:DataGridColumn headerText="name" dataField="currentAttribute.name" editable="false">

      For testing purposes I have the "Alert.Show" on mousedown in the grid which does work correctly. I'm shown the correct currentAttibute.name when something is slected.

      Is my syntax incorrect for the currentAttribute.name in the dataField or something?
