friendly_id / acts_as_referenced conflict?

Hi,

I'm using acts_as_referenced to generate unique references:

# property.rb class Property < ActiveRecord::Base acts_as_referenced :referenced_column => "permalink" end

I would now like to use friendly_id to create seo friendly URLs instead of using the id.

I now have:

# property.rb class Property < ActiveRecord::Base acts_as_referenced :referenced_column => "permalink" has_friendly_id :permalink, :use_slug => true end

The above code generates a "slug text is blank" error - I assume this is due to acts_as_referenced using a before_save callback to generate the permalink which friendly_id is looking for.

Is it possible to get the two plugins working together? Initialize the acts_as_referenced first?
