Hello,
I'm getting a weird behaviour of new ActiveRecord Models which I'd migrated on
this machine. The Model Class ist empty and i'm getting:
Loading development environment (Rails 2.3.4)

=> #<Navigation id: nil, lft: nil, rgt: nil, class: nil, name: nil, link: nil,
created_at: nil, updated_at: nil>
>> Navigation.create :name => 'menu.offers', :link => 'root_path', :class =>
>> 'sub_nav'
