The "Creating Modular Applications" chapter of the Flex Developer's Guide has undergone a major rewrite.
Download the new chapter's PDF: Creating Modular Applications
Enhancements include the following:
- Using modules in Flex Builder
- Passing data from the app to the module/from the module to the app/inter-module
- Preloading modules
- Using modules in ActionScript
Here's a ZIP file of all the code samples (full applications) used in the document: Code Samples.
Enjoy!

Great job guys.
You made an amazing job.
thank you
I've passed this on to Ted Patrick and others at Adobe -- The entire Flex team is doing a great job. Without the excellent documentation, I would not have been able to learn Flex so quickly. I read some part of the documentation every day and really appreciate the work everyone's done.
Its really great stuff guys .I had not used modules before but definately looking forward to it as the prospectus for my next project.
Best of luck and keep the good work going
