Abstract

An environment for developing clientside/serverside code is disclosed. The environment supports the perception that the server space and client space are seamlessly joined into a single program execution space. An outgrowth of the single execution space includes effective event handing on the server through enabling created objects to migrate effectively between the server and client.
