Hi,

I’m trying out the Asset Manager Demo extension with Mental branch and  
ran into a error. While I’m digging in, thought to see if anyone has  
any ideas

Background: I’ve got Rmagick, ImageMagick, acts\_as\_attachment installed  
and can see the “Assets” extension installed when I click on the  
Extensions link in admin.

When I click the new “Images” tab (courtesy with Asset Manager Demo),  
I’m presented with:

ArgumentError in Admin/assetController#index

A copy of Technoweenie::ActsAsAttachment::ActMethods has been removed  
from the module tree but is still active!

RAILS\_ROOT: ./script/…/config/…  
Application Trace | Framework Trace | Full Trace

#{RAILS\_ROOT}/vendor/rails/activesupport/lib/active\_support/dependencies.rb:234:in  
`load_missing_constant' #{RAILS_ROOT}/vendor/rails/activesupport/lib/active_support/dependencies.rb:447:in`const\_missing’

`acts\_as\_attachment’  
#{RAILS\_ROOT}/vendor/extensions/assets/app/models/asset.rb:7

Any ideas!?

Discovered this has nothing to do with Radiant or Asset Manager Demo.  
My bad, I apologize. Fixed when I dropped Rails back from latest to  
r5675
