"undefined method `abstract_class?' for Object:Class" with collectiveidea-awesome_nested_set and searchlogic

Reported by john (at psynix) | April 1st, 2009 @ 07:41 AM

I've run into a slight incompatibility with awesome_nested_set (1.1.1), searchlogic (1.6.4) and scoped acts_as_nested_set.

With everything in place:


class SomeModel < ActiveRecord::Base
  acts_as_nested_set :scope => :account
end

Calling any nested set method fails with:


NoMethodError: undefined method `abstract_class?' for Object:Class

If I remove either the :scope on the nested set or the searchlogic config.gem (installing as a plugin makes no diff btw) then it won't generate any errors.

TIA,

John
