The REST Resource class has got some minor changes before we removed its experimental tag. The single change we made is adding a way to invoke the request immediately when starting polling. The immediate call was the default before the change and needs now to be enabled using an argument.
// call get immediately, and then call it again every second (old API) resource.poll("get", 1000); // wait for one second, and then call it every second (new API) resource.poll("get", 1000); // old behavior with the new API resource.poll("get", 1000, undefined, true);
See the documentation of the new API.
