Hi, I have a problem with Rails 3.0.9. I am generating some concatenated javascript files with a runner, it is working flawlessly in Rails 2.3. With Rails 3.0.9 I get an Exception with this backtrace: actionpack-3.0.9/lib/action_view/helpers/asset_tag_helper.rb:794:in `rails_asset_id'' ... railties-3.0.9/lib/rails/commands/runner.rb:50:in `eval'': can''t convert nil into String (TypeError) The rails_asset_id method is using config.assets_dir to join it with the javascript file name, but config.assets_dir is nil and it fails. I''ve tried to set the assets_dir in various places, but without success. I also can''t find any documentation for this parameter. Does anybody has a clue, how one should set the assets_dir?
