i`m trying here to find some help to apply an JsonFormat extended of the DefaultJsonProtocol
to an class containing a Sequence of Objects.

So for the classes:

```
class Person(val name: String, [......], val adresses: Seq[Adress])
class Adress(val streetname: String, val plz: BigDecimal, val city: String)

```

now i would like to apply my JsonFormat:

```
object PersonJsonProtocol extends DefaultJsonProtocol {
  implicit object PersonJsonFormat extends RootJsonFormat[Person] {
    def write(pers: Person) = JsObject(
    "name" -> JsString(pers.name),
    [......],
    "adresses" -> JsArray(pers.adresses)
)
def read(value: JsValue) = {...}
}

```

But actually i am not sure how to do it. 
I searched through the spray-json documentation and throug google, stackoverflow & Co.
I am totally new to Scala/Spray and perhaps i am just missing the point. So perhaps somebody here is so kind to help me. Without the Adress sequence i will work.

With the JsArray as provided in the example i get an type mismatch. It is exspecting an List[JsValue] but also with converting to list the mismatch still stands.

I also tried to inserts an seperate AdressJsonProtocol and include it via:
"addresses" -> AdressJsonFormat.write(pers.adresses) but yet again it is an Sequence...
