ActionScript 3.0 :: Super Class Type - Override And Inheritance Chain

Lets say I have the following inheritance hierarchy:
Code:
Select allpackage {
public class ClassA {
protected function foo():void {
// do something
}}} package {
public class ClassB extends ClassA {
[Code] .....

Now this is all well and good, as the call to ClassC.foo() will propogate through the inheritance chain; C > B > A. But what if I want ClassC.foo() to call foo() that is in ClassA and bypass the method call in ClassB? I have tried the following:

* Cast the method to the super-class type I want to execute, but this does not work as intended.
Code: Select all...
override protected function foo():void {
// do something related to Class C
// call ClassA.foo
ClassA(this).foo();
}
