Re: [actionstep-core] subclassing NSMenu issues

That's a really good question. Most of the time, yes, you should call
super.init()...unless you're overriding something like initWithFrame,
in which case you should call super.initWithFrame().
And no, there isn't somewhere you should always look. But you must
call an initializer in the superclass, without fail. Sometimes things
will go very wrong if you don't.
And don't worry about asking questions. It just makes us think a
little bit. Ask away. :)
