AddObjectToAsset + HideFlags.HideAndDontSave

Hello !

I have an asset file that contains an array of "abstract class". I have read this post about serialization in unity : http://forum.unity3d.com/threads/serialization-best-practices-megapost.155352/

So my base class is abstract, derived from ScriptableObject, and have the hideFlags set to HideFlags.HideAndDontSave.

I use the method AssetDatabase.AddObjectToAsset(...) to store each object of the array in the assets file.

When I call AddObjectToAsset, Unity throws this error : !(o->TestHideFlag (Object::kDontSaveInEditor) && (options & kAllowDontSaveObjectsToBePersistent) == 0)

But everything seems to work fine. What does this error means, since I don't have any trouble using the assets created like this ?

Thanks!
