      I have this situation using v4 beta1:

      class Exercsie
   has_many :repetitions
end

class Repetition
   belongs_to :exercise
end

class ParticularRepetition < Repetition

end

      Based on some condition a push in repetitions a subclass of Repetition.

      This works:

      exercise.repetitions.push  Repetition.new

      This brakes with the following exception.

      exercise.repetitions.push  ParticularRepetition.new
ArgumentError: wrong number of arguments (1 for 0)
from ............mongoid-4.0.0.beta1/lib/mongoid/fields.rb:477:in `block (2 levels) in create_field_check'

      Am a doing something wrong or is a possible bug?
