Preferences can change in 2 ways -A gadget sets a preference which calls an RPC listener in the container letting the container know about the preference change or -A user changes a preference for the gadget in the containers UI
In either case it is up to the container to persist preferences for gadgets. In the second case where the user sets a preference in the containers UI the container should rerender the gadget with the new preference values. The OpenSocial Explorer has a pretty strait forward implementation of this. The ExplorerContiner [1] adds a function to the container config that will be called when a gadget sets its preferences. The PreferencesDialog [2] class then notifies the container when the preferences change which in turn causes the gadget to rerender.
