List View Filter / Scope by Has Many Association

[Eric Hochberger]

Is there anyway to add a filter / scope to only display results in in the list view for a has_many association? It currently gives me "undefined method `searchable_columns' for nil:NilClass " if I add :tags as a filters [:tags]

My Post has_many :tags :through => :taggings and I really need the ability to allow my users to choose a tag from a drop down and sort that way. Is it possible?
