Authorization plugin base_class method

Hi!

I'm using Rails 2.0.2 and i've install "authorization plugin", Now when I write something like this:

      @project = Project.new(params[:project])       if @project.save         @manager = User.find(params[:project][:user_id])         @manager.has_role "manager of :project", :project => @project

i'm getting error:

undefined method `base_class' for Hash:Class

vendor/plugins/authorization/lib/publishare/object_roles_table.rb: 62:in `get_role' vendor/plugins/authorization/lib/publishare/object_roles_table.rb: 32:in `has_role' app/controllers/projects_controller.rb:21:in `save' app/controllers/projects_controller.rb:16:in `save'

Any ideas why?

Ok, I see now that in plugin thinks @project is a Hash class. But when I display @project.class in my controller I get Project

so what it changes in some magic way??
