应用错误收集

在Scala 2.8和liftweb.net 2.0中我试图将一个case-class序列化为Json但是当case类中有一个枚举时它会失败。

import net.liftweb.json.DefaultFormats
import net.liftweb.json.Extraction._
import net.liftweb.json.JsonDSL._
import net.liftweb.json.JsonAST.JObject


// Enumerated type
object ColorType extends scala.Enumeration {
 type ColorType = Value
 val Red, Blue, Grean = Value
}

然后案例类 -

case class colorInfo (name : String, color : ColorType)

尝试转换为JObject的代码

val tColor = colorInfo("sienna",ColorType.Blue)
implicit val formats = DefaultFormats
val x = decompose(tColor).asInstanceOf[JObject]

我收到此错误：

在包含Enumeration类型的字段时，将scala案例类转换为json JObject时遇到问题
