Hey folks,
It seems there is a bug with hab2m relations appeared in 2.3.3. Say I've got models like that
class Model has_and_belongs_to_many :stuff field :text, type: String def text=(text) self.stuff = parse_stuff_from(text) super(text) end end
Meaning I'm assigning the stuff hab2m association by hijacking one of the attributes writer.
Then when i do the usual stuff in the controller
class ModelController def create @model= Model.new(params[:model]) end end
It crashes like that

It woke just fine before 2.3.3 and works fine if I do it like that in the controller
def create @model= Model.new @model.attributes = params[:model] .... end
After digging a bit into your code, it seems that the association accessor method returns nil instead of an empty array at the moment when the text attribute is getting assigned in the constructor.
Could you fix that please?
Thanks
