validates_uniqueness_of fails to recognise unique arrays. I think this is because ActiveRecord calls serialize on a property when it is an Array but validates_uniqueness_of is comparing the original property with the serialized version.

This workaround appears to work
validates_uniqueness_of :members, :scope => ''band_id'',
:message =>
"This line up already exists"
before_validation :serialize_members
after_validation :deserialize_members
def serialize_members
self.members.sort!
self.members = self.members.to_yaml
end
def deserialize_members
self.members = YAML::load(self.members)
end

For the moment I''ve added these two lines (st 552) to validations.rb
if condition_params[0].instance_of? Array
condition_params[0] = condition_params[0].to_yaml
end
Which appears to work but I haven''t tested.
