Cant use extended classes variables or methods?

[Doush.]

I have this problem from time to time with AS3 where I extend a Class and then try call methods and variables which are public from the new class but I get errors that method or variable doesn't exist. My IDE recognises the methods and variables though.

Heres an example

//I have a base class
public class Box {

   public var id:int;

   public function somemethod() {}

}

//Then I extend the class
public class BiggerBox extends Box {}

//Then in a separate class I try this
var bigBox:BiggerBox = new BiggerBox();

trace(bigBox.id);

bigbox.somemethod(); 

When I run the script flash hates it. I thought when you extend a class it was supposed to inherit its properties and methods?

Does anyone else have these problems? I shouldn't have to cast it as Box. I swear I have this working in a project but cant see the different in setup?

Where do you have the package in your classes? The code should otherwise work.

Well, Box and BiggerBox both site inside the same package

package com.site.boxes {}

but the class calling the bigbox.somemethod(); is inside another package

package com.site.logic {}

Actually I just searched and it was sort of a package problem.

The logic package already contained a class called bigbox and even though I imported com.site.boxes.BigBox;

The one in the package was overriding it.

Thanks for the help cancerinform. I appreciate it.

Had to be something like that, because otherwise it would not have made sense.
