aggegrates don't work in Ruby 2.0

[strallhofer]

require 'data_mapper'
require 'dm-migrations'
require 'dm-aggregates'

class DmNilTest
include DataMapper::Resource
property :id, Serial
property :test_value, Float
end

DataMapper::Logger.new(STDOUT, :debug)
DataMapper.setup(:default, 'postgres://elmar@localhost/dm_nil')

DataMapper.auto_upgrade!
DataMapper.finalize

DmNilTest.all.destroy
10.times do
DmNilTest.create(test_value: rand)
end

puts DmNilTest.aggregate(:test_value.min, :test_value.max, :test_value.avg).inspect

SQL statement is the same both in Ruby 1.9.3 and 2.0.0:
SELECT MIN("test_value"), MAX("test_value"), AVG("test_value") FROM "dm_nil_tests"

but in the latter case the result is [nil, nil, nil]

@strallhofer Try using the latest release-1.2 branches for dm-core, dm-aggregates and any other DM gems you use.

I believe this is a typecasting issue which was recently fixed. If the problem persists please let me know.

Hi Dan,

I tested again, with dm-core, dm-aggregates and dm-postgres-adapter, all with branch "release-1.2", and now it works!
Thanks a lot for the quick fix!
