Problem modulating action script project

I am refac开发者_如何学Gotoring a hugh action script solution in Flash builder (beta 2) using the flex 4 sdk. The project does NOT use the mx framework.

What i want to have is:

• A big 'MAIN' project
• several small 'MODULE' projects. each 'MODULE' class refrences the 'MAIN' project as an External reference (doesnt compile into swf) - this is done by setting link type = external in the 'MODULE' project properties -> library path.
• 'MAIN' loads a 'MODULE' project on runtime using the 'loader' class.

the problem: I recieve an error from the MODULE project:

VerifyError: Error #1014: Class [some class in MAIN] could not be found.

PLEASE HELP!

Check which application domain you are loading your module into. The app domain needs to be able to access the class you have externalised or you'll get that error.

It might just be a bug with the beta version of the sdk. It seems like the import of a class in a module created in another project doesn't force it's inclusion in the main swf.

try putting a dummy dependency in you main application class, like:

private var forcedImports:Array = [MyClass];

It fixed some of my problems before.
