Using swfupload with the Playframework and a Mac - file-upload

Question

I am trying to implement SWFUpload using the Play! framework and a Mac.
When using a Mac I get a 302 error (Upload Error: 302). This seems, I think, to come from the redirect that happens by getting the upload page of the Play! framework (as it is translated from the routes file?).
It works fine on IE on Windows.
I have searched a lot, and read a lot, but haven't found if there is a particular solution. Are there any suggestions on how to implement this, or any suggestions for another simple to implement file uploader (for big field, with progress)?
EDIT:
I have tried both Safari and Firefox on my Macbook and both return as status the 302 upload error. I tried again on Windows with IE and it works fine.
The html (stylesheet) code:
#{extends 'main.html' /}
#{set title: 'Upload Media File' /}

#{/form}
The entry in the routes file (the Articles.upload is the screen, the doUpload is called by swfupload):
GET /admin/articles/{id}/upload Articles.upload
POST /admin/articles/doUpload Articles.doUpload
EDIT 2:
I also tried Uploadify, which returns the same error. Is there anybody who knows a workaround for the Play! framework or an uploader that does work with Play!

Answer 1

If you are in /admin/articles/{id}/upload and call doUpload without any /path/to/something, you're in the wrong "directory". Might it be that you test Windows locally, but MacOS remotely?
In any case, the problem most probably has nothing to do with the OS, but with something else.

Answer 2

There is html 5 uploader at http://www.uploadify.com which can be downloaded for $5, and it works perfect for me so far.
