When I add it, compiling fails. I get "Error: Can not resolve a multiname reference unambiguously. JSON ...". It apparently finds JSON in both the SDK/frameworks/libs/air/airglobal.swc and in JSON.as in a temp folder created when I compile. I tried renaming one file, then the other, didn't help. Anyone see this issue or have any ideas? using SDK 184.108.40.206, AIR SDK 3 (and i changed the line to 2.7) If I remove that feature, the app compiles just fine.
