3. Incomplete SDK Installation

A partial installation of Flex 3.6 or Flex 4.x without the required automation or advanced data visualization components can trigger a patch listing failure when the SDK tries to reconcile missing SWCs.

1. Introduction to the Patch List Mechanism

In Flex 3, the compiler does not simply compile files in isolation. It builds a dependency graph. When you use CSS or load Modules, the compiler maintains a "patch list" to ensure that definitions (like class styles, skins, and effect definitions) are applied in the correct order.

A Patch Listing Error generally implies that the compiler or runtime has detected an inconsistency in how style definitions or component definitions are being patched into the application. This often happens when a definition exists in the main application and is subsequently re-defined or "patched" by a loaded module or CSS file in a way that violates the hierarchy of the ApplicationDomain.

3.4 Recreate the Patch Definition

If the patch is required:

<!-- Example: patches/MyPatch/patch.xml -->
<patch>
    <replace file="src/Main.mxml" />
    <add file="src/NewComponent.mxml" />
</patch>

Then re-add it via Project Properties → Flex Patch Build Path.

3. Verify Patch Order (if using official Adobe patches)

Patches for Flex 3 must be applied in numerical order:

  • Example: 3.0.1 → 3.2 → 3.4 → 3.6 Never skip a version.
