Making a Grails domain class with JS Objects inside?

Question

I'm wondering how I would create a Grails domain class with JavaScript objects as variables on the inside of the class.

For example, I am sending a JSON object that looks like this:

{
   "name":"task",
    "type":{
       "label":"Work",
       "id":1
    },
    "priority":{
       "label":"Mid Priority",
       "id":2
    },
    "completed":false,
    "comments":"",
    "creator":"user",
    "assignedTo":"user"
}

As you can see, "type" and "priority" are objects in their own. My grails domain class looks like this currently:

package server

class Item {

   //String username
   String name
   String type
   String priority
   boolean completed = false
   String comments
   String creator
   String assignedTo

   static constraints = {
       name nullable: false
       priority nullable: true
       type nullable: true
       comments nullable: true
       creator nullable: false
       assignedTo nullable: false
   }
}

Obviously the string is incorrect, but I don't know what it should be? Right now everything is saved as it should be in the JSON list except for the type and priority.

For the SQL DBs no other alternatives other than saving the JSON as a string exist. All solutions have marshalling/unmarshalling at some stage, but the data is still stored as a TEXT or BLOB in a table.

NoSQL DB-s like mongo do allow you to store the BSON object as it is.
