Class flash.media::CameraRoll could not be found

[xTLS]

I'm working on an iOS app using AIR3.3 and Flash Professional. I've been editing class files in Flash Builder 4.6, but debugging in Flash Builder. Now I want to try profiling the app from FB, but when I try to do so, I get the error Main Thread (Suspended: VerifyError: Error #1014: Class flash.media::CameraRoll could not be found.)

I'm guessing I need to link to a library or something, but I'm not sure what or how.   The application compiles and runs correctly from Flash Pro, and the CameraRoll functionality works fine when I publish the IPA from FP and run it on the device.

Someone, please?

Still wondering...
