Do you mean that you're moving from Flex 2 to Flex 4? Or from Flex 2 to Flash 4? They mean radically different things. I'm going to assume you mean the former.

Did you download a trial of Flash Builder 4? You said you hit a wall; what wall did you hit?

When you say that "Web Services Not Using Live cycle"; I'm not sure what that means. But to me that sounds like it might be a problem with your server side code.

It would be my expectation that compiling a Flex 2 application against the Flex 4 SDK would present relatively few problems.

Hi all,
I would like to see our current code base updated from Flex 2.0.1 to Flash 4. We have many bugs inherent to the components in the SDK I would like to see resolved. The project is quite large...using web services and many many components(and States..I think these guys changed).

I downloaded the trial for Flash 4 and tried to port some of our code over, but immediately hit a wall with the web services not using live cycle. So I am looking for some thoughts from you guys...aside from some of the web services being broken, am I looking at a whole of change? How much backwards compatibility does this migration support.

Thanks so much for any suggestions.

Jenn
