    Adobe flex Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.


      fileRef =

      new FileReference();

      fileRef.addEventListener(Event.SELECT, fileRef_select);


      fileRef.addEventListener(Event.COMPLETE, completeHandler);



      This code threw exception in firefox but not in IE. Since i was uploading to a https server, which had fake or self signed certificate, firefox upload used to fail. When i changed to port 8080 and tried uploading, it worked on firefox.  On our production server where I have a real certficate this does not fail.

      So my solution is either get use a real certificate if you upload to https or else just do a http and it will work.
