Facet on join field

[calinoiu....@agilefreaks.com]

Hi,

I have the following models

class CoreWindow
  searchable do
    join(:alpha_sort, target: Epixcms::Movies::Movie, type: :string, join: {from: :movie_id, to: :movie_id})
  end
end

class Movie
    searchable do
        string :alpha_sort
    end
end

The following searh works as expected

search = Movie.search do
    facet :alpha_sort
end

search.facet(:alpha_sort).rows # is ok

But the following does not work

search = CoreWindow.search do
    facet :alpha_sort
end

search.facet(:alpha_sort).rows # is empty

Looks to me that facet on join fields does not work am I missing something?

Regards,
