Entity `Nothing` is not registered #67

Hi, guys,

I am pretty much new to sorm framework and decided to try it because of its API simplicity but unfortunately get this exception during 'fetch by id' operation. Please provide some advice on code below:

  object Database extends Instance(
    entities = Set(Entity[Post]()),
    url = config.getString("db.url"),
    user = config.getString("db.user"),
    password = config.getString("db.password"),
    initMode = if (config.getBoolean("db.init")) InitMode.DropAllCreate else InitMode.DoNothing
  ) {}

import org.h2.tools.Server
import org.scalatest.{BeforeAndAfterAll, Matchers, WordSpec}

class DatabaseSpec extends WordSpec with Matchers with BeforeAndAfterAll {

  "Database" should {

    "provide value by id" in {
      val post = Post("title", "azaza")
      val saved = Database.save(post)
      println(Database.fetchById(saved.id))
    }
  }

  override protected def beforeAll(): Unit = Server.createTcpServer("-tcpAllowOthers").start()
}

Please find full stack trace below:

What's the definition of Post?

kelebra · 2016-03-08T14:47:44Z

Post is just case class:
case class Post(title: String, content:String)

Hmm.. Which version of Scala are you using?

2.11.7
