Inner classes do not work properly

[mhdirkse]

In my Codegen program I has an annotation @input() where referenced the name of an inner class. The Codegen program gave an error when the inner class was referenced by its canonical name, which is without "$" sign. The plugin error was fixed when the class was referenced by its ordinary name, which is with "$" sign. But that way, I got a compile error in my output class. It inherited from , but now you do not need the "$" sign.
