Object reference not set to an instance of an object.

[GoogleCodeExporter]

On the client side, i connect to the server. Then from the server side i 
approve the connection and send a remotehailmessage. Then, from the client 
side, the line right after the connect line is:

identification = client.ServerConnection.RemoteHailMessage.ReadInt32();

(This is so that the clients can be differentiated.)

But the client gives me the error: Object reference not set to an instance of 
an object. because the hailmessage is null!

Please help me, and tell me if you need all of the code for both.

You should check out the Chat sample; it uses a hail message. It only does 
client->server hail, but I just verified server->client hail, and it works fine.

Could you give me a link to it, please?

It's in the Samples folder of the source code; you'll need SVN to access it:

Well, I tried to follow it by changing my code to this:

                else if (recv.MessageType == NetIncomingMessageType.StatusChanged)
                {
                    NetConnectionStatus status = (NetConnectionStatus)recv.ReadByte();
                    if (status == NetConnectionStatus.Connected)
                    {
                        identification = recv.SenderConnection.RemoteHailMessage.ReadInt32();
                    }
                }

but it still says the same error about the hail message being null.
From the server side I just have it be:

                    if (recv.MessageType == NetIncomingMessageType.ConnectionApproval)
                    {
                        send = server.CreateMessage();
                        send.Write(pos.Count);
                        recv.SenderConnection.Approve(send);
                    }

It's probably something simple I didn't even know about..

The code you posted looks ok; not sure what goes wrong.

Thanks for trying to help anyway :). Maybe someone else knows. Maybe it's not 
the code.
