Acts_as_versioned conflicts?

Rails
1

Dear list,
At the moment I am building a simple RESTful wiki. For this I am using
Edge Rails. I have a simple Page model which has a couple of
associations and acts_as_*. One of them is acts_as_versioned and that
one is misbehaving.
I should be able to call something like: Page.find_versions(14), this
should return an array of Pages, each a different version. However it
returns an array with elements of the Page::Version class(OK I can
live with this). Also;

p = Page.find(:first)
p.find_version(1)
Raises an error:
NoMethodError: undefined method find_version' for #<Page:0x34f57b0> from /*/vendor/rails/activerecord/lib/active_record/ attribute_methods.rb:205:inmethod_missing’
from (irb):54
from :0
And that is correct:

p.methods.sort.select {|m| m=~/find/}
=> []

I am pretty sure I got everything right as I copied most of it from
Rails Recipes.
The Page model looks like this:

class Page < ActiveRecord::Base
acts_as_versioned
self.non_versioned_columns << ‘project_id’ << ‘project_user_id’ <<
‘locked_by’ << ‘locked_at’ << ‘created_at’ << ‘updated_at’
acts_as_tree #POSSIBLE CONFLICT

belongs_to :project
belongs_to :project_user

validates_presence_of :title, :text, :project_user, :project

end

Am I doing something really dumb?
Thanks for any help!

Just to loop back on my own post. I no longer believe it is a confict.
A clean Rails 1.2.5 project with only acts_as_versioned also failed to
find the method ‘find_version’. This leads me to believe the plugin is
broken in that respect. Too bad.

It’s a class method, not an instance method. If there was an instance
method, it might have been removed since it’s no longer necessary.

In that case the Rails Recipes book is wrong. I took recipe 20 and
there they do something like:

chapter = Chapter.new
…

chapter.find_version(1).title

So what is the recommended way to get your hands on an old version?
I am now using something like this:

@page = Page.find(params[:id])
version = Page.find_version(params[:id],params[:page][:version])
@page.revert_to(version)

This works but is hardly the way I would expect it to.
