AS 2.0 Classes and Linkage

In my project i have to classes that inherit the MovieClip class. Then I create a movie clip and in the library i click on linkage and I set on AS2 class field the name of the first class. Inside this movie a create another movie clip and I set his AS2 class to the second class. The problem is, when i run the file the properties of the nested movie clip are not available for the parent. What a mean is that in the constructor of the first class I cannot acces the methods of the nested movie clip. Somehow i need the nested movie clip to be initialized first and then the parent. Can anyone give me a solution or am I doing something wrong …
