Usually, validation is handled in itemEditEnd and not itemFocusOut. Posting the actual stacktrace will help. Use a debug build so we can see line numbers

Moreover when i enter the 'Enter' key it throws an error #1009, findNextItemRenderer() Thanks, with Regards, Jitendra Jain Software Engineer 91-9979960798
