Hi Vijay,


Thank you for your prompt response.  I cannot reproduce either.  I created a new app and used your documentation code.  Works fine.


Let's close the ticket.  If I ever have any such experience and details, I will share with your team.


Thanks once again and sorry for the inconvenience I cause to you.


Harshad
