For those who use FDT within Eclipse and are still managing AS2 projects, you might notice that your AS2 core lib doesn’t have the mx framework in it. If you attempt to go and code AS2 using any of the framework (components, etc.) your project will show up broken.

This is a simple issue to fix, but I’ll point out how for the non power users.

1. Create a folder on your drive to be considered as your core actionscript lib (ex: C:\tools\flash\core_lib).

2. Copy the contents of FP8 folder and mx folder itself from your FDT install (ex: {ECLIPSE INSTALL}\configuration\com.powerflasher.fdt.core\.config\core\as2) to the core lib

3. In Eclipse go to your preferences > FDT > core libraries > as2 core libraries

4. Either edit the current core lib or add another one and point it to the lib you created

5. eat some snacks and get ready to code.

Hope this is of help to someone who might get confused with it.
