I am building a Flex application that loads other Flex and Flash applications. The problem comes in with the legacy Flash applications, there are explicit references to _level0, 1, & 2 throughout the code base. Historically, the Flash application has a base container which is expected to be at _level0, then a middle layer and a top application referencing down to _level0.
What I'm seeing is once a version 7 Flash app. is loaded by Flex the legacy Flash has no visibility to _level anything.
I have tried SwfLoader and Loader with and without LoadContext ApplicationDomain.
