I don't understand why. In Javascript, if you assign an object or an array to multiple variables, you haven't actually copied the object or array; you've just saved a reference to the object or array in the multiple variables. var a = [ 1, 2, 3 ]; var b = a; a[0] = 23; console.log(b[0]); // will print 23 You can use the static method qx.lang.Array.clone() to clone an array. The static method qx.lang.Object.clone() will non-recursively clone an object (i.e. if any of the object's members is itself an array or object, those will not be cloned by this method). Using the above example: var a = [ 1, 2, 3 ]; var b = qx.lang.Array.clone(a); a[0] = 23; console.log(b[0]); // will print 1 Derrell
