Hi Booma Devi,
I dint mean that actually
I was referring to line 28 in the first mxml where you have
<mx:RemoteObject id="serv" destination="remoteGrid" fault="faultHandler(event)"/> defined. Here I dont see a result handler being declared, so I thought that would be the mistake.
As you have used the same strings('name', 'age') in datafields of mxml as well as attributes of class Person, I dont think there is a need to create an actionscript mapping class.
Thanks,
Praveen.
