Could you point us to where in the book you find this lovely line?

If I'm not mistaken, you need to add an onAnswer: block to the editor :=
line of code:
   editor := person asComponent
     addValidatedForm;
     onAnswer: [ :p | "do something with p" ];
     yourself.

To explore further put a self halt in the block to see when it gets called.

Also, I don't think you need to send initialize after you send new.
And be sure person and browser are returned in an array in the children
method.

Look at the bright side: You aren't in Java anymore =)
