Problem with adding field to GameConnection

I have scoured the forums and cannot quite find the answer I am looking for. Basically I added my own class and then added a field to GameConnection so that it could hold a pointer to that object. I wrote the proper code to allow this method to be used in the script but I am having a problem. When I try to access this field in a GUI element it always returns NULL. I did not write any code to communicate to the client that that field changed so I am guessing my problem lays there. My question is how would I achieve this. I see that the player class does it with write and read packet data. However GameConnection does not seem to have this method, my best guess is the similar readPacket and writePacket. Anyway if anyone can let me know if that is my problem, and/or point me in the direction of how to solve my problem I would greatly appreciate it.
