I am also having this issue. When I click to add new object, it creates it fine and displays it within my form. Say if I click remove object. It disappears and while inspecting the html page it shows that its hidden.

Once I try and click submit, it comes back to that same page showing that the object didn't pass validations, while the params it was sending to the server showed "_destroy"=>"1".

Was wondering how to get around this problem.

I believe this is due to do how Rails 4 access param field. In your Controller you can do this as a quick work around.

def product_line_params
      #TODO: Fix this as it is unsecure.
      params.require(:product_line).permit!
    end

Read this, it is part of Rails 4 core now: https://github.com/rails/strong_parameters
