Advanced datagrid question

Question

Hi All,
I have an ADG displaying items in groups showing totals for each group using:
          private function summFunc(cursor:IViewCursor, dataField:String, operation:String):Number{
                var sumAll:Number = 0;
                while (!cursor.afterLast)
                    if (dataField == "Amount")
                        sumAll += Number(parseFloat(cursor.current["Amount"]));
                    cursor.moveNext();
                return sumAll;
          <mx:dataProvider>
            <mx:GroupingCollection id="groupedData" source="{acSampleADG}" >
                <mx:Grouping>
                    <mx:GroupingField name="Series" >
                        <mx:summaries>
                            <mx:SummaryRow summaryPlacement="last" summaryObjectFunction="summObjFunc">
                                <mx:fields>
                                    <mx:SummaryField dataField="Amount" summaryFunction="summFunc" />
                                </mx:fields>
                            </mx:SummaryRow>
                        </mx:summaries>
                    </mx:GroupingField>
                </mx:Grouping>
            </mx:GroupingCollection>
        </mx:dataProvider>
Amount column is editable. If I change the value for an item the total for the group is not updating.
How can I refresh that value?
Thanks
Johnny

Answer 1

I figure out to skip the error in my ITEM_EDIT_END event.
Now if I use groupedData.refresh() it puts the old values back. Is this a bug?
Any ideas?

Here is my fuction for  ITEM_EDIT_END event.
private function update_ADG_values(event:AdvancedDataGridEvent):void{
    var grid:AdvancedDataGrid = event.target as AdvancedDataGrid;
    if(event.dataField=="Amount"){
        acSampleADG.refresh();
        myADG.validateNow();
        var myEditor:TextInput = TextInput(event.currentTarget.itemEditorInstance);
        var newVal:Number = parseFloat(myEditor.text.replace(",",""));
        var oldVal:Number = Number(event.itemRenderer.data[event.dataField]);
        if (event.reason == DataGridEventReason.CANCELLED || event.reason == DataGridEventReason.OTHER || oldVal == newVal) {
            event.preventDefault();
            grid.destroyItemEditor();
            return;
        groupedData.refresh();
