Flex Spark DataGrid GridItemEditorSessionSave Event issue - apache-flex

Question

I have a strange problem in Flex s:DataGrid/>. The gridItemEditorSessionSave event triggers two times for me. The minimum code to recreate this issue is below:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Declarations>
<s:ArrayCollection id="dp">
<fx:Object test="Test"/>
</s:ArrayCollection>
</fx:Declarations>
<fx:Script>
<![CDATA[
import spark.events.GridItemEditorEvent;
protected function onGridItemEditorSessionSave(event:GridItemEditorEvent):void
{
trace("Edited >>>", event.columnIndex);
}
protected function onGridItemEditorSessionStart(event:GridItemEditorEvent):void
{
trace("Edit Start >>>", event.columnIndex);
}
]]>
</fx:Script>
<s:DataGrid dataProvider="{dp}" width="100%" height="100%" editable="true"
gridItemEditorSessionSave="onGridItemEditorSessionSave(event)"
gridItemEditorSessionStart="onGridItemEditorSessionStart(event)">
<s:columns>
<s:ArrayCollection>
<s:GridColumn dataField="test"/>
</s:ArrayCollection>
</s:columns>
</s:DataGrid>
</s:WindowedApplication>
When I edit the cell, the trace statement is as below :
Edit Start >>> 0
Edited >>> 0
Edited >>> 0
Which indicates onGridItemEditorSessionSave triggers twice! Not sure I am missing anything.
Any help appreciated, thanks in advance!

Yes, it seems like a bug. There are other reports for this : http://apache-flex-users.2333346.n4.nabble.com/spark-Datagrid-GridItemEditorEvent-firing-twice-td3582.html
As mentioned in this discussion I have done a workaround by setting a flag _goForCellEdit=true in the ItemListEditStart event and checked this in gridItemEditorSessionSave event. Hope will help if some one ran into the same problem.
