Subject: Re: array of objects within an object

Hello,

I think you  need to define to_s methods for your
Port, State and Owner classes. These to_s methods
should return a string representation of the class
they belong to (e.g. the state of the current object's
instance variables). The Object#inspect method will
then call these methods when invoked, instead of
calling Object#to_s

hope this helps,

Brian
