Hello all,
This link:
http://datamapper.lighthouseapp.com/projects/20609/tickets/524-lazy-loading-error-in-through-associations
said, that error is fixed.
However, when I'm trying to access a Text field in a model (One-To-
Many-Through), I have error:
merb : worker (port 4000) ~ can't modify frozen array - (TypeError)

My models:
class Product
include DataMapper::Resource
storage_names[:default]='Products'
property :id, Serial
property :name, String, :length => 255
property :article, String, :length => 60, :nullable => false
property :created_on, DateTime, :nullable => false
property :weight, Integer, :default => 1000000, :nullable => false
property :quantity, Integer, :nullable => false
property :price, Float, :nullable => false
property :image_url, String, :length => 255, :nullable => false
property :image_width, Integer, :nullable => false
property :image_height, Integer, :nullable => false
property :annotation, Text, :nullable => false, :lazy => true
property :description, Text, :nullable => false, :lazy => true
property :video, Boolean, :default => false, :nullable => false
has n, :tagging
has n, :tags, :through => :tagging
end
class Tag
include DataMapper::Resource
storage_names[:default]='Tags'
property :id, Serial
property :name, String, :length => 60, :nullable => false
property :weight, Integer, :default => 0
has n, :taglinks, :child_key => [:source_id]
has n, :child_tags, :through => :taglinks, :class_name =>
"Tag", :child_key => [:target_id]
has n, :tagging
has n, :products, :through => :tagging
end
class Tagging
include DataMapper::Resource
storage_names[:default]='Tagging'
property :product_id, Integer, :key => true, :nullable =>false
property :tag_id, Integer, :key => true, :nullable =>false, :index
=> true
property :weight, Integer, :nullable =>false, :index => true
belongs_to :tag
belongs_to :product
end
ps: if i disable lazy in Product model (:lazy => false) all OK.
