Can loaded swfs reference static methods of container.swf?

Hello,
I have a Container.swf that is responsible for loading in other Content.swfs. I defined a Container.as file as the document class for Container.swf, and created a few static methods that I want to have available for the Content.swfs. I figured that after a Content.swf is loaded, I could just reference those methods like so :

Container.myStaticMethod(“var1”, “var2”);

but I am getting a compile time error which I understand fine, but wasn’t expecting it, since it wasn’t thrown with AS2.

1120: Access of undefined property Ground

I also tried Stage.myStaticMethod(“var1”, “var2”); which yields pretty much the same result.

Do I need to import my class Container.as class in each of my content.swfs?

Thanks in advance
