Ajax request does not support FormData (html5)

[heyarny]

I have tried the Ajax request as suggested by Manolo himself at: http://stackoverflow.com/questions/21088340/file-upload-with-a-progress-bar-or-accessing-the-html-5-file-api-from-google-we But unfortunately this solution doesn't seem to work. At least not with current version of gwtquery. Using his solution body being sent is just empty.

For now I've created my own XMLHttpRequest wrapper and it works just fine.
