解答：
Just thought I'd add that I've run into this error in the past specifically when compiling with the command line compiler or with flex ant tasks. I was experiencing an issue where FB's built in compiler would compile without errors, but the command line/ant compilers would return with the "Invalid Embed" errors. It turned out that for some reason the command/ant compilers were having difficulty resoloving abosolute paths such as '/assets/images/myImage.png'. I was able to resolve the errors by changing the absolute path references to relative path references such as '../../../assets/images/myImage.png' in files that were reporting errors.
