Call derived function from base contract

Question

I have the following smart contracts:

pragma solidity ^0.4.11;

contract base {
    uint public v;
    separate public mySep;

    function base() {
        mySep = new separate();
    }

    function f() {
        v = 1;
    }

    function sepCall() {
        mySep.doStuff();
    }
}

contract derived is base{
    function f() {
        v = 2;
        super.f();
    }
}

contract separate {
    derived myBase;

    function separate() {
        // constructor expects to be called by base or derived
        myBase = derived(msg.sender);
    }

    function doStuff() {
        myBase.f();
    }
}

I only create an instance of derived which I expect to do the following:

1. call base constructor base()
2. base constructor creates instance mySep of separate contract

Now I am calling sepCall of that derived instance which I expected to do the following:

3. it calls the doStuff function of the separate contract.
4. the doStuff calls the overridden function f of the derived contract (since that's its type)

The last point is not happening, after calling sepCall of the derived instance its value v is 1 and not 2 which it would be if the overridden function of derived would have been called.

This might not be solidity related but a general JS issue but I'd like to find out how I could make sepCall invoke the overridden function f that sets v to 2.

Reading your code, V = 1, because after you set V=2 you then call super.f() which sets it to 1.
