Android Realm Retrofit relationship error

I am having an issue getting all of my POJOs and everything setup so that it parses my JSON correctly.

I am fairly new to Android development so the fix could be something simple.

I was able to get this to work without Realm. I think modified my POJOs to extend RealmObject. My issue is with my relationships. My data is setup so I have a WorkOrder class and a WorkOrderItem class. A WorkOrder contains many WorkOrderItems. Without realm I define this in my POJO as

private List<WorkOrderItem> workOrderItems = new ArrayList<WorkOrderItem>();

When I modify this to extend a RealmObject I start running into issue. I have tried

private RealmList<WorkOrderItem> workOrderItems;

As well as 

private RealmList<WorkOrderItem> workOrderItems = new RealmList<WorkOrderItem>();

Either way I continue to receive the following error:

Error:(831, 82) error: incompatible types: List<WorkOrderItem> cannot be converted to RealmList<WorkOrderItem>

I have setup my GsonConverter as suggested in the documentation.

I have read through all of the documentation and everything I can find online and still have not found a solution. Any help on this would be greatly appreciated.

On request the callback you're probably getting a List <WorkOrderItem> So I think you need to create your Realmlist <WorkOrderItem> from your list.

you need have two Objects WorkOrderItem and other WorkOrderItemRealm extends RealmObject

For instance :

List<WorkOrderItem> mWorkOrderList...
RealmList<WorkOrderItem> mRealmList... //WorkOrderItem need to be a RealmObject


...new Callback<List<WorkOrderItem> mWorkOrderList>() {

    @Override
    public void success(List<WorkOrderItem> mWorkOrderList, Response response) {

        for(WorkOrderItem mWorkOrderItem : mWorkOrderList){

            //create WorkOrderItemRealm
            WorkOrderItemRealm mWorkOrderItemRealm = realm.createObject(WorkOrderItemRealm.class); 

            //mWorkOrderItemRealm.set...(mWorkOrderItem.get...());

            mRealmList.add(WorkOrderItemRealm);
        }
    }

    @Override
    public void failure(RetrofitError error) {

    }
});
