You have to extent GroupingCollection . It's a bug
package {
import flash.events.Event;
import mx.collections.*;
import mx.events.CollectionEvent;
import mx.events.CollectionEventKind;
public class ModifiedHierarcihcalData extends GroupingCollection
{
public function ModifiedHierarcihcalData()
{
}
override public function set source(value: Object): void
{
super.source = value;
this.refresh();
}
}
and use as in this example
<mx:AdvancedDataGrid id="adg" groupLabelFunction="grpFunc"
visible="true"
headerHeight="40"
lockedColumnCount="0"
horizontalScrollPolicy="on"
verticalScrollPolicy="on"
sortExpertMode="false" width="100%"
height="100%"
creationComplete="dgrefresh();callLater(expandFirstNode);" >
<mx:dataProvider>
<extns:ModifiedHierarcihcalData
id="gc" >
<mx:Grouping>
<mx:GroupingField
name="{viewSelection.selectedItem.data}">
<mx:SummaryRow summaryPlacement="group">
<mx:fields>
<mx:SummaryField
dataField="{viewSelection.selectedItem.data}" operation= "COUNT"
label="summary"/>
</mx:fields>
</mx:SummaryRow>
</mx:GroupingField>
</mx:Grouping>
</extns:ModifiedHierarcihcalData>
</mx:dataProvider>
