@sankar: Can you try upgrading to DM 0.10.1 and let me know if the problem persists? All of the code related to the bug you are reporting was rewritten to resolve this problem (among others).

it works fine in version 0.10.1, but i have used dm-sweatshop for fixtures, i got undefined method error
cattr_accessor' in<br/> dm-sweatshop/lib/dm-sweatshop/unique.rb line no: 66 -

@sankar: what version of extlib do you have? Can you make sure you've got the latest version (0.9.13) installed? Are you able to require 'extlib/class'? Can you try explicitly requiring it before requiring dm-sweatshop?
The extlib package adds cattr_accessor to the Class object. I'm not sure why it's not happening in this case.

@sankar: If you try all of the above and it still doesn't work, can you update your sample script with some code that reproduces the error for you everytime?

@dkubb: sorry, the error is not in sample code, it is my application, I didn't put require 'extlib/class' in my application. i'm not aware of that. thnaks for your help. it works fine now
