I've created a swc library. Opening this swc, I can extract the library.swf.
Placing library.swf on my server and using it as an RSL, everything works fine.
If I run optimizer against the library.swf, the resultant library-optimized.swf does not work as an RSL. I get
Flex Error #1001: Digest mismatch with RSL
...
Redeploy the matching RSL or relink your application with the matching library.
in the log.
Is there something I am missing about creating a working optimized rsl swf? I've tried linking against every piece of metadata I can find.
