Not sure whether this is truly a bug, but when I search for "scala is not an enclosing class", the top hit claims that this represents a (family of) bugs in the Scala type checking system: http://stackoverflow.com/questions/5143849/scala-is-not-an-enclosing-class

At any rate, here's the code that produces the message:

object Test {
  import net.liftweb.json.JObject
  import net.liftweb.json.JsonDSL._
  val map: Map[Int, String] = Map(1 -> "one")
  val json: JObject = ("myMap" -> map)
}

The error message would be clearer if it gave some clue that the problem is that you can convert from a Map[String, ?] to a JObject, but not a Map[Int, ?].

Have you tried with Scala 2.9.x? It seems like a duplicate of #3152, which eventually was fixed.

this one's probably both cannot reproduce and fixed
i'm pretty sure about the former (i don't have lift lying around)
and Johannes hinted at the latter

Sorry, I forgot about this issue until I got the notification from Adriaan Moors. I just tested on 2.9.2, and I indeed get a more precise compile error now.
