What ever you add to the business process context has to be serializable. The business process engine saves the entire context to the database so that it can be resurrected at any time. We are counting on this capability for our fail over contingency. You need to come up with a strategy that a fully functional context can be serialized out and remarshalled and function as if nothing had happened. You need provide enough serialized information for the reinstantiation of non-serializable objects and make your code capable of doing the reinstantiation.
