[errai-users] Use of RequestDispatcher

This has been a long time coming (since before 1.0). The use of RequestDispatcher's when sending messages instead of directly referencing the MessageBus is now strongly-encouraged. In fact, new API extensions (such as the async API) will no longer introduce APIs that use the MessageBus directly in terms of sending messages. The current APIs remain backwards compatible. But use of request dispatchers will make your application more scaleable, by allowing messaging to be sent truly asynchronously from your code. As opposed to directly performing operations against the bus in the same thread from whence you send your messages. You can simply inject a RequestDispatcher just like you're used to injecting a MessageBus. public class MyClass { private RequestDispatcher dispatcher; @Inject public MyClass(RequestDispatcher dispatcher) { this.dispatcher = dispatcher; } public void sendAMessage() { MessageBuilder.createMessage() .toSubject("Foo").signalling().noErrorHandling() .sendNowWith(dispatcher); } } ... and in the client, you can obtain an instance to the RequestDispatcher with: ErraiBus.getDispatcher(); Best, Mike.
