Re: adding filter to file upload in gwt

I'm actually surprised that it worked; what browser, and how did it
represent that setting to the user?

Keep in mind that there's no guarantee that this will work in all
browsers; the W3C spec says only that this "provides the user agent
with a hint of file types to accept". How it does that is up to the
browser, and the browser is free to give the user the option to select
any file, notwithstanding your list of acceptable MIME types. So
you're still going to want to validate the file when the user clicks
the submit button.

http://www.w3.org/TR/html-markup/input.file.html

ⓘ accept = list of MIME types
Provides the UA with a hint of what file types the server is able to
accept.
A set of comma-separated strings, each of which is a valid MIME type,
with no parameters.
