Unpermitted parameter: :tags

[sedubois]

I tested this plugin with Administrate 0.12.0 as follows:

# tag_catalog.rb
class TagCatalog
  def self.all
    [
      Tag.new(id: 'tag1', name: 'Tag 1'),
      Tag.new(id: 'tag2', name: 'Tag 2')
    ]
  end

  class Tag
    attr_accessor :id, :name
    def initialize(id:, name:)
      @id = id
      @name = name
    end
  end
end

# dashboard
  ATTRIBUTE_TYPES = {
    ...
    tags: Field::CollectionSelect.with_options(
      collection: proc { TagCatalog.all },
      value_method: :id,
      text_method: :name,
      options: {
        include_blank: 'Please select some tags',
        include_hidden: false,
      },
      multiple: true,
      label: 'Tags'
    ),

The form loads great, but the selected value does not get saved and the logs show Unpermitted parameter: :tags. It appears that the permit method is filtering out this parameter because it's an array (see code).
