Initialize an object with an array

Answer 1

I guess you failed adding the method new: correctly to Frame class. Are you sure you put it on the class side (Frame class) and not on the instance side (Frame)? To do it, click on the 'class' button, before adding your method new:.

Answer 2

You really don't want to override new: here. new: is traditionally reserved for "Create an item of this integer size", and it doesn't surprise me that it's blowing up on you.

A more traditional name for the kind of constructor you want is fromArray:, or perhaps even fromCollection: which would probably have worked as you wished.
