FileItem with addChangedHandler

[bc]

Hi,

I am using FileItem to upload files to the server. I use the 'addChangedHandler' event handler to do a form.saveData to upload files.
The addChangedHandler event seems to fire multiple times (3 times) and as a result it uploads the file twice and for the last request
it just hangs. On the dev console it says 'Request in progress'. Why is the event firing multiple times and how do I handle it?

I am using SmartGwt Pro 5.0p (v10.0p_2015-04-03/Pro Deployment (built 2015-04-03))

Thanks.
Bk.
