I guess I have the bad luck of coming to Flex at a bad time.
I have never used Flex so I do not have Flex 2. It did not occur to
me that the Beta for Flex 3 was meant only for Flex 2 users. I just
happen to be evaluating RIA tools for a new project. From what I
was able to see I am very impressed by the Flex/Flash platform. It
just surprises me that Adobe would put such a short expiration on
the beta. So the question remains unanswered.
