Commented Issue: AjaxFileUpload - calls first upload_complete on page [27234]

I had multiple ajax file uploads on a page with seperate upload_complete methods. however when upload first using the 2nd or third uploaders, it always still called the upload_complete of the first control
Comments: I have the same issue, multiple AjaxFileUpload controls on one page, the sender of the server side UploadComplete event is always the first control on the page. This is having a high severity impact for me. Does anyone have a workaround for this yet?
