Archiving the Controller

Hey all,

I'm having some difficulty archiving my controller. My controller is being used to run a genetic programming simulation that controls a 6-legged robot. It has a PushInterpreter and a population of PushGPIndividual's. The documentation on archiving simulations left me a bit confused. Do I need to do anything other than create an archive function that returns 1 and save the controller via save-as-xml? When I try that the PushInterpreter errors on archive. Any suggestions?

Thanks
