Mixing AS and Flex in CS3

Hi,

I have done a project on AS3 in Flash CS3 which is using:

  • library items with class linkage
  • timeline instances
  • a lot of as3 classes (inherited from linkage)

Now I need to add some user interface elements such as dialog boxes, alert messages etc. which I found Flex can easily provide me.

The actual question is - can I simply import Flex libraries in Flash CS3 by adding class paths and use functionality from actionscript files? If no, what is the correct way of adding Flex assets into my existing CS3 project? I don’t really want to leave Flash because I like animation/visualisation/drawing tools in CS3.
