Created Unassigned: Use of Multiple AjaxFileUpload In Page [27850]

I need to use more than one AjaxFileUpload in a page. I create a usercontrol to do this.

I need to know which uploader is uploading which files so I add a property FileType.

If I place multiple instances of AjaxFileUpload in a page, only one is being read for both instances. So, when uploading files for uploader1, the FileType of Uploader1Type is read. When uploading files for uploader2, still, FileType of Uploader1Type is read.

Is this a bug or is this on purpose? I need to get the filenames of each file uploaded and get which uploader is concerned, how should I go about it?
