In one implementation, a system caches view custom options in a framework to support web-based applications. A set of server-side objects is managed by an object manager (OM) running on a server. A set of browser-side objects runs on a browser running on a client. A remote procedure call (RPC) mechanism enables re-targeting of methods from browser-side objects to server-side objects. A notification mechanism facilitates transmission of notifications from server-side objects to browser-side objects. A cache on the client stores custom options of views.
