Formtastic::UnknownInputError

[futuretap]

Installed the formtastic_jquery_ui (0.0.4) gem in addition to the (already working) formtastic 2.0.0 on rails 3.1.0 and configured

 = f.input :categories, :as => :autocomplete, :url => categories_path(:format => :json), :param_name => 'title_begins_with'

Then I get a Formtastic::UnknownInputError. Do I have to edit config/initializer/formtastic.rb file to let formtastic know of the extension?

I learned that Formtastic 2.0.0 introduced some big changes for plugins.
Details here: http://richardhulse.blogspot.com/2011/06/upgrading-to-formtastic-20.html

Will your plugin be compatible with Formtastic 2.0 anytime soon?

I've switched to simple_form for all new projects, and as such this project is dormant.

If you want to fork it and submit patches I'll take a look, but other than that I can't guarantee that I'll be able to fix this anytime soon.
