Hi folks,

this seems such a simple issue, i just made a video of it, check [here](http://www.michalfiala.com/data/tmp/).  
\*[this will be removed when the issue is fixed, so for other folks looking for the trivia, read on]  
\*

Problem:  
Using Flash CS3 IDE for library assets, connecting them with behavioral model in AS files…

Having 2 classes, 1 that extends the other which in turn extends ‘DisplayObject’, the library assets can be traced in the class that inherits, but not in the base class that is being extended (there we get ‘null’ when tracing the assets).

Question:  
how to get references of the library assets into the base Class, so that they can be handled in the base Class?

Thanks folks!
