Can't activate a prefab from an EditorWindow ?

Hi !

I have a problem with SetActive(), and I don't know how to solve this.

I have created a window for activate / desactivate gameobjects by tags. Hide objects was really easy and work perfectly with this script :

 GameObject[] objectsList = GameObject.FindGameObjectsWithTag("MyTag") as GameObject[];
 for (int currentId = 0; currentId < objectsList.Length; currentId++)
 {
     objectsList[currentId].SetActive(false);
 }

So I need to reactivate ALL of the objects of the scene, so I've made a method with this :

 GameObject[] objectsList = Resources.FindObjectsOfTypeAll(typeof(GameObject)) as GameObject[];

 for (int currentId = 0; currentId < objectsList.Length; currentId++)
 {
     objectsList[currentId].gameObject.SetActive(true);
 }

Here is the problem : the gameobject are reactivated, but not the gameobject linked to a prefab (blue color on the Hierarchy). I've made many tests, but those log maybe should help :

 GameObject[] objectsList = Resources.FindObjectsOfTypeAll(typeof(GameObject)) as GameObject[];

 for (int currentId = 0; currentId < objectsList.Length; currentId++)
 {
     objectsList[currentId].gameObject.SetActive(true);
     Debug.Log(objectsList[currentId].gameObject.activeSelf);
 }

The result was really clear : all gameobjects returns "true" event if they're not activated. I have tried to use SetDirty after the SetActive, but it doesn't change anything ...

Someone can help ?

Thank you !
