I have a newly coded GWT/GAE app that uses RequestFactory and Editors on the client and a custom Objectify DAO Service on the back. The flush() then persist() paths work fine on success. Client side JSR 303 works as well as can be expected too. My question is how to trigger server warnings/errors and handle UI updates? I am using Chandler's Generic DAO for Objectify 2 at http://turbomanage.wordpress.com/2010/02/09/generic-dao-for-objectify-2/ my gwt activity is calling persist( myProxy ).fire( new Receiver<> ) my dao code is throwing IllegalArgumentException and other RuntimeExceptions for business logic situations like "Duplicate email address found - want to login instead?" Receiver<>.onSuccess() works fine to track a successful outcome. neither Receiver<>.onFailure() nor Receiver<>.onViolation() report the RuntimeExceptions. Is there a better way to do this? What exceptions should the DAO throw such that onViolation() or onFailure() report errors? How should the editor(s) handle and recover from the exception? -- -- A.
