Hi,

We're sorry about that. Seems it is a bug. Because the MIDlet works fine without that line.

But could you send us the code snippet, then we'll check it for you.

Regards

Hello,

Thanks for your reply. Here I am attaching the source code. Please let me know if somethings is wrong.

Thanks a lot,

Andrés.
