Question

I have a complicated application. I use Flex 4.1 RSLs and custom RSLs for all my libraries (and there are like 15 of custom SWCs – Flex Library Project)

I would like to load main application with minimal RSLs needed and then load Flex Module with all other RSLs in the background while users interacts with first part of app.

Main app needs 3 SWCs, Module needs rest of them (12).

If I have one Flash Builder Apllication project with Application.mxml where I have all RSLs linked (as RSLs) and Module.mxml

How do I solve this, so RSLs are loaded with the Module into child application domain?

Currently I am using:

info = ModuleManager.getModule(URL);
info.load(new ApplicationDomain(ApplicationDomain.currentDomain));

… so it should load into new App domain, but RSLs are preloaded into parent domain already!.

I am using static fields/singleton in my Module so I can’t load more of them.

If I could load Module with its RSLs into child app domain, Class definitions would separate and I could use two Modules, each with its own static fields.

Solution came with Flex 4.5 — Introduction to RSLs

Using placeholder RSLs

When you compile an application with
Flex, the default behavior is to
compile the application against the
framework (or default) RSLs. When the
application runs, it loads only the
framework RSLs that it actually uses,
and creates placeholders for the
remaining framework RSLs. When the
application loads a module or
sub-application that requires one of
the framework RSLs for which there is
a placeholder, the module or
sub-application then loads that RSL
into the main application.
