Received state update for view ID AllocatedID: but no init

i have non allocated boxes in scene

Code (csharp):

1.  
2.         GameObject[] cts = GameObject.FindGameObjectsWithTag("Box");
3.         for (int i = 0; i < cts.Length; i++)
4.         {
5.             GameObject a = cts[i];
6.             a.AddComponent<NetworkView>();
7.             a.networkView.observed = a.rigidbody;
8.             a.networkView.stateSynchronization = NetworkStateSynchronization.ReliableDeltaCompressed;
9.             a.name += i;                        
10.         }
11.  

when player take box function called:
AssignID(i, Network.AllocateViewID()); // i: box index

Code (csharp):

1.  
2.     [RPC]
3.     public void AssignID(int i, NetworkViewID id)
4.     {
5.         CallBuffered(Group.Rig, "AssignID", i, id);
6.         GameObject g = GameObject.FindGameObjectsWithTag("Box")[i];        
7.         g.networkView.viewID = id;
8.         g.networkView.observed = g.rigidbody;
9.        
10.         Trace.Log(IsMine + "Assinged network id" + g.networkView.viewID);
11.     }
12.  
13. public void CallBuffered(Group group, string fc, params object[] prs)
14.     {
15.         if (networkView.isMine)
16.         {
17.             networkView.group = (int)group;
18.             networkView.RPC(fc, RPCMode.OthersBuffered, prs);
19.         }
20.     }
21.  
22.  

on both sides allocated ids are correct and owners too

on server side works fine , but on clients side i get error "Received state update for view ID AllocatedID: * but no initial state has ever been sent. Ignoring message."

what wrong i do? what this error means?
