Rails - Mar 2006 - strange has_many array problem

I have a class that has_many :visits, I want to search through the  
visits to get only ones that are committed:
I thought it would be as easy as:
=================   visits.find_all do |visit|
     visit.coming?
   end
================
but this always returns the entire list of visits. The only way to  
get it to work is to put the visits into a new array first:
================   Array.new(visits).find_all do |visit|
     visit.coming?
   end
=================
Can someone explain this to me?

Hi John,

Using your example:

visits.each do |visit|
   visit.coming?
end
