Plupload / flash / Amazon S3 / unique_names

Question

I am working on a plupload implementation using flash to upload files to Amazon S3. I have a file upload on S3 that works fine except for one small problem. The problem is that the "unique_names" parameter is not working. I always get the file in S3 with the original file name. After some debugging, I see that a unique file name is created and passed to Flash SWF for download, but it is never used. Any help would be greatly appreciated.

You can check if the file is unique before downloading the file. Here is my code.

UploadFile: function(up, file) {
        pluploadlog('[UploadFile]', file);
        // You can override settings before the file is uploaded
        var filename = file.name;
        file.newname = '01'+ filename ;///add your own function here to create something unique. 
         up.settings.multipart_params = {
                   'key': mybucketsubdirectory + filename, 
                  'Filename': filename, 
                  'acl': 'public-read',
                  'Content-Type': 'image/jpeg',
                  'AWSAccessKeyId' : '<?php echo $accessKeyId; ?>',
                  'policy': '<?php echo $policy; ?>',
                  'signature': '<?php echo $signature; ?>'
                };
      },

Then, upload the file.newname file added earlier to the file.

FileUploaded: function(up, file, info) {
          if (file.status == 5){
             console.log(file.newname); // If you need to get back the new unique name
            uploadSuccess(file, info); 
          }else{
            showItemError(file);
          }
        }
