One deadly mistake possible while executing this. ,
November 29, 2008 at 7:20 AM

Hi.

Yesterday one friend of mine copied this code and tried to execute this after making some slight(in fact not slight at all!!!!) changes. He was getting some error message. On correcting it i found that he had declared the state variable of type List again inside the execute function!!! I just removed it and the code started working!!! This was just to inform to avoid such mistake.
