Hi all,

I got the following error, while trying to upload.

SEVERE: Terminal error:

Is there anyone has an idea about this issue?

Thanks

Could be the same issue as
http://vaadin.com/forum/-/message_boards/view_message/494612
- the sending and handling of upload streams has changed somewhat and your application might be using the wrong version of the widgetset.

If that is not the issue, try upgrading to the latest 6.5 version (or to 6.6) - I would recommend upgrade in any case - and see if you can still reproduce the problem.
