Re: [salat] Serializing/Deserializing custom types wrapped in Option?

Sorry, Yusuke, looks like a bug.  I will investigate after work today.

Hi,

I have a problem trying to serialize/deserialize custom types wrapped in Option.

The problemn is that `asDBObject` or `asObject` itself runs but doesn't seem to use my custom transformer.

I'm currently using Scala 2.9.1 with the Salat 1.9.2-SNAPSHOT.

And my custom types:

```

package example

case class Foo(value: String)

```

And my serializing/deserializing code and results:

```

import example.{Foo, Doc1, Doc2}

import com.novus.salat.{Context, grater}

import com.mongodb.casbah.Imports._

import com.novus.salat.transformers.CustomTransformer

val fooTransformer = new CustomTransformer[Foo, String] {

  def deserialize(b: String): Foo = Foo(b)

  def serialize(a: Foo): String = a.value

}

implicit val context = new Context {

  val name: String = "foo"

  registerCustomTransformer(

    fooTransformer

  )

}

/** Not O.K. The custom transformer is NOT USED for `foo` */

val doc2Grater = grater[Doc2]

doc2Grater.asDBObject(Doc2(Some(Foo("value"))))

//=> {"foo": {"value": "value"} }, but expected {"foo": "value"}

doc2Grater.asObject(DBObject("foo" -> "value"))

//=> Doc2(None), but expected Doc2(Some(Foo("value")))

/** This is O.K. The custom transformer is used for `foo` */

val doc1Grater = grater[Doc1]

doc1Grater.asDBObject(Doc1(Foo("value")))

//=> {"foo": "value"} as it is expected.

doc1Grater.asObject(DBObject("foo" -> "value"))

//=> Doc1(Foo("value")) as expected

```

Am I missing something?

Thanks,

Yusuke

Has this been fixed in 1.9.2-SNAPSHOT?
