spriteselector callback not working

[loverains]

if (spriteName != sprite.name)
                     {
                        if (mSprite != null)
                        {
                           NGUIEditorTools.RegisterUndo("Atlas Selection", mSprite);
                           mSprite.spriteName = sprite.name;
                           mSprite.MakePixelPerfect();
                           EditorUtility.SetDirty(mSprite.gameObject);
                        }
                        else if (mCallback != null)
                        {
                           mName = sprite.name;
                           mCallback(sprite.name);
                        }
                     }
                     else if (delta < 0.5f) close = true;
the callback block should not use else if ,just if would be ok!
