AdvancedDataGridRendererProvider

Question

I have been at this all day everyday for almost a month. I have an ADG filled with an arrayCollection from a RO. I have read all about the AdvancedDataGridRendererProvider I can get the column spanning and the right row but not the right data. I read that this works:
note: the data I want is REMA2W (this is a long description) this is called summaryRenderer.mxml
<mx:Canvas 
xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Label id="rowLabel" textAlign="left" width="100%">  
<mx:Script>
<![CDATA[
override public function set data(value:Object):void { 
super.data = value; 
rowLabel.htmlText = data.REMA2W;
]]>
</mx:Script>
</mx:Label>
But sadly it does not. If I do this: rowLabel.htmlText = data.GroupField; I get the data but its not what I want.
This is my renderer:
<mx:rendererProviders> 
<mx:AdvancedDataGridRendererProvider dataField="REMA2W" columnSpan="5" columnIndex="0" depth="1"renderer="SummaryRenderer"/>
</mx:rendererProviders>
How do I see what the data that is available to me is?
This is my ADG:
<mx:AdvancedDataGrid  id="adg" defaultLeafIcon="{null}" displayItemsExpanded="true" width="100%" height="100%" themeColor="#73B9B9" initialize="gc.refresh()">
 <mx:dataProvider>
 <mx:GroupingCollection id="gc" source="{myWine}">
 <mx:Grouping groupingObjectFunction="grpObjFunc">
 <mx:GroupingField id="gf" name="myHeader">
 <mx:Array id="summ">
 <mx:SummaryRow summaryPlacement="group">
 <mx:fields>
 <mx:SummaryField dataField="REMA2W" label="REMA2W"/>
 <mx:SummaryField dataField="myList" operation="SUM" label="myTotal"/>
 </mx:fields>
 </mx:SummaryRow>
 </mx:Array>
 </mx:GroupingField>
 </mx:Grouping>
 </mx:GroupingCollection>
 </mx:dataProvider>
 <mx:groupedColumns>
 <mx:AdvancedDataGridColumn dataField="CMPT2W" headerText="Item" width="110"/>
 <mx:AdvancedDataGridColumn dataField="DESCRIP" headerText="Desc"/>
 <mx:AdvancedDataGridColumn dataField="SDIVDE" headerText="Size" width="50"/>
 <mx:AdvancedDataGridColumn dataField="NOFF2W" headerText="Btls" width="50" textAlign="right"/>
 <mx:AdvancedDataGridColumn dataField="BPRC5W" headerText="Inc BBC" width="60" textAlign="right" />
 <mx:AdvancedDataGridColumn dataField="myList" headerText="List" width="60" textAlign="right" />  
<mx:AdvancedDataGridColumn dataField="myTotal" itemRenderer="NumberItemRenderer" headerText="Cost" width="60" textAlign="right"/>
 <mx:AdvancedDataGridColumnGroup headerText="Inventory">  
<mx:AdvancedDataGridColumn dataField="INV_41" headerText="Morgan Hill" width="60" textAlign="right" visible="{myDetail.selected}"/>
 <mx:AdvancedDataGridColumn dataField="INV_31" headerText="Chino" width="60" textAlign="right" visible="{myDetail.selected}"/>
 </mx:AdvancedDataGridColumnGroup>
 </mx:groupedColumns>
 <mx:rendererProviders>
 <mx:AdvancedDataGridRendererProvider dataField="REMA2W" columnSpan="6" columnIndex="0" depth="1"renderer="
com.esria.samples.dashboard.view.SummaryRenderer"/>  
</mx:rendererProviders>
 </mx:AdvancedDataGrid>
I have read that the data. property has all the elements from the row. I just dont know how to see them.
EVERYTHING in my app works perfect except landing the REMA2W in the group and in the 2nd column.
Thanks

Answer 1

Summary rows are generated by the GroupingCollection so they do not contain the same sets of fields as your data rows. In your example your summary rows will contain the following fields:
GroupLabel - the label for your group as defined by your GroupingField
REMA2W - a summation of all the REMA2W fields in the corresponding group
myTotal - a summation of all the myList fields in the correspinding group
children - an array of the group's child rows
I'm basing this on the "Creating Summary Rows" section of the link below (search for "Internally, the GroupingCollection"):

Previously I asked you to put in the following debug code:
for ( var property : String in data )
     trace( property + ": " + data[ property ] );
You replied that you saw the following: grouping label, the cost field, an NaN and an Object. That's 4 fields as expected. Unfortunately you did not follow the instructions exactly so we got no property names. I would suggest trying again to get property names and values using this approach.
