Monkey patching with acts_as_journalized (development environment) (Bug #1148)

In Development Environment, no known issue in Production Environment
I am creating a plugin that would add journals to Version. When attempting to view activity or a user's page, the first view works fine, but a reload causes "Association :project not found". When I put my acts_as_journalized code in version.rb, the issue does not occur.

Code:

module CoreUpdate
    module VersionPatch
      def self.included(base)
        base.class_eval do
          acts_as_journalized :event_title => Proc.new{|o| "Milestone Update ##{o.version}"},
            :event_description => Proc.new{|o|
            str="" 
            o.details.each do |detail|
              str<<"#{o.render_detail(detail,true)}\n" 
            end
            str
          },
            :event_url => nil,
            :activity_permission=>:manage_milestones
        end
      end
    end
  end
