Can't receive JSON response with YUI file upload in Struts2

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create file upload using struts2 and YUI as defined here:
http://thecodecentral.com/2007/09/04/asynchronous-file-upload-yuis-approach
2. Create response, defining <result type="json" /> in struts.xml
3.

What is the expected output? What do you see instead?
I expect my javascript callback to receive the json string.  What happens
is the browser (ff 3) prompts me to download myAction.action.  This is
because the content-type is "application/json".  If I change the response
type to something else (like plain text), My callback gets the event.

What version of the product are you using? On what operating system?
json plugin 0.31 on Windows XP, Mac OS X

Please provide any additional information below.
If I could simply set a parameter to something like <parameter
"content-type">text/html</parameter>, that would likely solve the problem.  

The fundamental problem is that for a file upload, struts is creating an
iframe, which doesn't understand the content-type.  So it prompts the user.
