It looks that your next form - mite is null, is it initialized before? Where is it created?

[raj_J2ME]

Command cmd1 is not initealized, can you try to create the same and test?

Thank You ektasrv. I have cleared my issue. Actually i was initialized that form in another if block. That's why this error occurs.

Also Thank You Raj.
