Object lists loaded through the Editor are empty at the start of runtime

Unity Engine

I’m using scriptable objects to build a set of actions and resources, and I’ve loaded these into two lists using the editor interface.

The parent object DataController is the first thing to load (as a persistent object in the first scene), but even polling the list property on the first line of its create method returns an empty list:

[SerializeField]
public class DataController : MonoBehaviour {

public Resource resourceList;
public Action actionList;

private PlayerData playerData;

private string gameDataFileName = “data.json”;

// Use this for initialization
void Start () {
Debug.LogWarning(actionList);
Debug.LogWarning(resourceList);
…

Both debug warnings return empty lists

I’m pretty new to Unity so I must be missing something here in how either scriptable objects or the editor itself works. Anyone have any ideas? Many thanks.

EDIT: Fixed by changing Arrays to List<> objects. Not sure exactly arrays wouldn’t work though.

Arrays should work as well, are you sure it was empty?
You must check actionList.Lenght to be sure or use a for loop and log all entries:

Debug.Log("Array has "+array.Length+ " entries");
for (int i = 0; i < array.Length; i++)
{
    Debug.Log(i+": "+array[i]);
}

Also if the inspector shows the values then they are there.
