Switching from CS4 to flex

Question

I have a game I've written in AS3 class files. I've been
compiling with CS4. The first frame of the main timeline has one
line of code that calls a static method on a class, and passes it
"this" (the main timeline). This is all the code the .fla contains;
the .as files do everything. However, there are visual assets in
the library of the .fla that the code needs to instantiate. Some of
these assets are linked to class files, and some are not. In other
words, say I have LinkedClass.as linked to library symbol, and
another library symbol which is being exported for actionscript
with no corresponding .as file, so the NonLinkedClass is
automatically generated when the .fla is compiled. My static method
contains both "new LinkedClass()" and "new NonLinkedClass()".
I've set up an actionscript project in flex with one new
class that I didn't have before when I was using CS4. In the
constructor for this class, all I have is the same line of code I
had on the first frame of the main timeline before, the static
method that gets passed "this". (Does "this" still refer to the
main timeline? In other words, is the class I'm compiling in my
actionscript project in flex becoming the main class of a swf?)
1. Is this even the right way to go about doing this? I'm
pretty lost here. I've gone through tutorials having to do with
MXML, but I'm not sure what relation they bear, if any, to what I
want to do. How do I make something that compiled in CS4 compile in
flex? (Keeping in mind, I have custom classes linked to library
symbols, and also library symbol with no custom class, for which
classes are defined automatically when CS4 compiles.)
2. When I tried to compile the flex project, I got an error
for NonLinkedClass, so I used CS4 to compile a .swc and added that
.swc to the library for the flex project, and then I no longer got
the error for NonLinkedClass. However, I continue to get errors for
LinkedClass. LinkedClass has variables defined in the .as file, and
display objects are assigned to those variables because I've put
display object instances inside the library symbol LinkedClass is
linked to and named them after the variables. This works fine when
I compile with CS4, but with flex, these variables are coming up
null. I tried adding this code to LinkedClass.as
[Embed(source="pathToMyGameSwf/game.swf",
symbol="LinkedClass")]
but I get an error
"An Embed variable must not have an existing value."
Am I anywhere near the right track? Is there a tutorial
for this problem specifically, that is, trying to port a
project from CS4 to flex?

Hi Joachim,
I suggest that you post this question on the Lightroom forum: Photoshop Lightroom.
