Datamapper DataMapper

Using the UUID type from dm-types as a primary key throws an exception (below). The UUID type in general seems to work just fine when :key is not set.

I am defining the key as:

property :id, ::DataMapper::Types::UUID, :key => true, :unique_index => true, :default => lambda { ::UUID.random_create }

This was tested using 0.9.7 as well as the latest install from dkubb's fork of dm-core. Attached is the full script that can be used to replicate the problem.
