The problem seems to be this:

• When uploading a file, you must use a form post instead of an ajax request
• The result of the form post is handled by the browser instead of javascript
• Our server responses have content type application/json
• Firefox automatically prompts the user to save when it receives content of type application

The strategy recommended by the GWT documentation is to set content type to text/html, which can be intercepted and parsed by all browsers. (see below) John changed the results of document/create and campaign/create to have content type html/text which seems to have fixed the problem. (deployed on mdev1)

For reference, here's the gwt info:

From: http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/FormPanel.html

FormPanel

public FormPanel()
Creates a new FormPanel. When created using this constructor, it will be submitted to a hidden <iframe> element, and the results of the submission made available via FormHandler.
The back-end server is expected to respond with a content-type of 'text/html', meaning that the text returned will be treated as HTML. If any other content-type is specified by the server, then the result html sent in the onFormSubmit event will be unpredictable across browsers, and the FormHandler.onSubmitComplete(FormSubmitCompleteEvent) event may not fire at all.

Tip:
The initial implementation of FormPanel specified that the server respond with a content-type of 'text/plain'. This has been intentionally changed to specify 'text/html' because 'text/plain' cannot be made to work properly on all browsers.
