Compiler Errors in TextField of lime

I’ve got these problems when I was trying to use text filed.
Eventually I figured out FlashDevelop imported the wrong package for TextField, adn I’ve imported opefl’s packages, and everything worked fine. But I still don’t understand, what are those classes, and why do they have compiler errors?
