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?
