title: Salat and Embeded MongoDb Documents
body: <p>I have a case class that is made up of 2 embeded documents, one of which is a list. I am having some problems retriving the items in the list.</p>
  
  <p>Please see my code below:</p>
  
  <pre><code>package models
  
  import play.api.Play.current
  import com.novus.salat._
  import com.novus.salat.dao._
  import com.mongodb.casbah.Imports._
  import se.radley.plugin.salat._
  import com.novus.salat.global._
  
  case class Category(
    _id: ObjectId = new ObjectId,
    category: Categories,
    subcategory: List[SubCategories]
  )
  
  case class Categories(
    category_id: String,
    category_name: String
    )
  
  case class SubCategories(
    subcategory_id: String,
    subcategory_name: String
  )
  
  object Category extends ModelCompanion[Category, ObjectId] {
    val collection = mongoCollection("category")
    val dao = new SalatDAO[Category, ObjectId](collection = collection) {}
    val CategoryDAO = dao
  
    def options: Seq[(String,String)] = {
      find(MongoDBObject.empty).map(it =&gt; (it.category.category_id, it.category.category_name)).toSeq
    }
  
    def suboptions: Seq[(String,String,String)] = {
      find(MongoDBObject.empty).map(it =&gt; (it.category.category_id, it.subcategory.subcategory_id, it.subcategory.subcategory_name)).toSeq
    }
  }
  </code></pre>
  
  <p>I get the error: <code>value subcategory_id is not a member of List[models.SubCategories]</code> which doesnt make any sense to me.</p>
