[1.8] NetworkDispatcher exception on Multiplayer only

Hi there,

 

I'm having problems with sending packets between the Server (Container) and the Client (Gui). Each time a button is pressed in the GUI it sends a packet to the server so the container can alter the item in its slot accordingly. On the other side the container sends a message to the client, so the GUI can display the status of the item/ the changes made to the item.

 

The strange thing: In Singleplayer everything works just fine. If I open my world to LAN and somebody else is joining everything is ok for me, it still works. But as soon as he (the player who joined my world) opens the GUI and the first packet is exchanged he gets kicked. If he runs a world with my mod in Singleplayer on his own he has no problems.

 

The errors occuring are eiter like that:

[12:30:29] [Netty Client IO #3/ERROR] [FML]: NetworkDispatcher exception
io.netty.handler.codec.DecoderException: The received string length is longer than maximum allowed (24 > 20)

 

or like that:

NetworkDispatcher exception
io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(28) + length(1) exceeds writerIndex(28): UnpooledHeapByteBuf(ridx: 28, widx: 28, cap: 28)

 

I have no idea, why the message should be to long... I'm sending one Integer and recieving one Integer.

I tried to add different MessageIds for server and client when registering the Message (doesn't work).

I searched the forums and via google but couldn't find anybody having the same problem or a solution that worked for me...

So help would really be appreciated :) Does anybody have an idea what the problem is?

 

His error log:

I'm pretty sure the error is because your SimpleNetworkWrapper channel name exceeds the maximum length of 20.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
