sessions.withSession { session =>
println(“session = ” + session)
println(session | (“aaa”, new ColumnPath(“column1″, null, “bbb”.getBytes(“UTF-8″))))
}
}
}

It compiles well but got runtime exception:

keyspace = keyspace1
schema = {column1={CompareWith=org.apache.cassandra.db.marshal.BytesType, Desc=, Type=Standard}}

I am using AKKA 2.8.0.Beta1. 0.9 and Scala 2.8.0RC.

Any idea where I did wrong?
