Hi,  
I am having troubles using an extended class:  
Class B extends class A (that extends MovieClip)  
Class A defines a series of public static consts  
I’d like to use the A consts through the B instance, but they are not visible.

i.e.:  
A defines

```auto
public static const testString: String = "test";

```

```auto
testInst = new B();
trace(testInst.testString);

```

gives me an error, as if testString was not public.

Why? Am I missing a very stupid detail?
