I haven't used multiple connections myself, but I think you have two issues,
1) The default connection identifier is "lift" so you have to define a
connection with that name otherwise you'll have to override all Mapper
objects to use a different connection.
2) Your dbCalculateConnectionIdentifier method should look like,
override def dbCalculateConnectionIdentifier = {
case _ => Two
}
meaning, regarless of the mapped object's value, use connection "Two".
and if you always use the same connection for all objects of a given mapper
(i.e., you're not sharding) then you can alternatively override the
MetaMapper object's dbDefaultConnectionIdentifier method.
Hope this helps,
