Exception while trying to use jsonFormatxxx with a case class

[alexgenon]

Using Spray-Json 1.3.2 (note : I also had a similar problem with 1.3.1) While trying to output a case class as an object, I encounter an exception The test code import spray.json._ import DefaultJsonProtocol._ case class test(b:Boolean) val t=test(false) jsonFormat1(test)(t)

The exception I have is error: not enough arguments for method jsonFormat1: (implicit evidence$1: spray.json.DefaultJsonProtocol.JF[Boolean], implicit evidence$2: ClassManifest[test])spray.json.RootJsonFormat[test]. Unspecified value parameter evidence$2. jsonFormat1(test)(t)
