Redmine

In the class MessageObserver, there is a line to compact the list of recipients

recipients = recipients.compact.uniq

The purpose of this line is to make recipients array contains each item once. But I found I still have duplicate items in message_posted (class Mailer). I don't know why so I have to change it:

    parsed = Array.new
    recipients = recipients.select do |m|
      next if parsed.include?(m.user.id)
      send_mail = check_if_user_want_to_receive_mail(m)
      parsed << m.user.id
      send_mail
    end.collect{|m| m.user.mail}

and then I don't have any duplicated items anymore in recipients. I amnot sure but I think this problem is due to Rails/Ruby.

Hope this helps.
