[Moo] this.parent() class constructor in IE

[Oren]

Hey guys- It seems that in

var Cat = new Class({
    Extends: Animal,
    initialize: function(name, age){
        this.parent(age); // calls initalize method of Animal class
        this.name = name;
    }
});

from http://mootools.net/docs/core/Class/Class

the "this.parent()" function throws an "Object doesn't support this
property or method" error in IE7 and 8.

Anyone know how to get around this?

I appreciate it.

Oren
