[flexcoders] AutomationNameValue in intemRenderer : QTP Crashing

[Dharmendra]

Hello All,        I have a checkBox and a ComboBox based item renderer
in datagrid. As soon as QTP automated script clicks on checkbox
(Itemrenderer) or select a value from Cbox(itemrender) , QTP crashes.  I
have tried to set automationNameValue  by overriding
icreateAutomationIDPart in itemrenderer as suggested by adobe in
following link

<http://livedocs.adobe.com/flex/3/html/help.html?content=functest_compon\
ents2_16.html>    Basically , I have overridden createAutomationIDPart
method in both itenrederer              import
mx.automation.IAutomationObject;
             override public function
createAutomationIDPart(item:IAutomationObject):Object {
                     var id:Object = super.createAutomationIDPart(item);
                     id["automationName"] = id["automationIndex"];
                     return id;
             }
      QTP continues to be crashed even after overriding above method .
Please suggest some ways/ideas to solve this issue.   Flex Version - 3.2
Thanks & Regards
