[LRUG] Flex/Rails and downloading data to a file

Thu Apr 29 03:49:09 PDT 2010

I've tried both and didn't work. Maybe using amf you can't use them... IWhat
I'm trying now is to create a tempfile in rails and send the path to flex,
although I'm encountering a problem in flex when I try to do the download in
Flex:

Certain actions, such as those that display a pop-up window, may only be
invoked upon user interaction, for example by a mouse click or button press.
at flash.net::FileReference/download()

Just because I'm getting the file between the user clicking download and
flex invoking the download...
