Totally makes sense. In other words: make recoverPanelFromHistory async, with a callback passed as an argument rather than returning a value; and if data is cached, then just use the callback synchronously (of call it from a Scheduler.scheduleFinally if it makes you nervous to have your async call actually be synchronous) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
