Hi,
I'm using errai 1.3.0.CR1 and communication between client and server looks like this:
client code
(sending message)
MessageBuilder.createMessage().toSubject(DEPENDENTNUMBERS_SERVICE)
.signalling()
.with(MessageParts.ReplyTo, DEPENDENTNUMBERS_CLIENT)
.with("selectedNumber", baseNumber).errorsHandledBy( new ErrorCallback( ) {
@Override
(1) public boolean error( Message message, Throwable throwable ) {
throwable.printStackTrace( );
return true;
}
} )
.sendNowWith(dispatcher);
server code
(receiving message and sending response)
@Service
public class DependentNumbersService implements MessageCallback {
...
@Override
public void callback( Message message ) {
throw new AuthenticationException("you are not logged in yet!");
}
}
client code again
(receiving message)
erraiBus.subscribe(DEPENDENTNUMBERS_CLIENT, new MessageCallback() {
@Override
public void callback(Message message) {
dependentNumbers = message.get(List.class, "subnumbers");
view.showDependentNumbers(dependentNumbers);
}
});
The problem is that I can't catch exception raised on server side (AuthenticationException).
The method bookmarked in code as (1) is not handling the exception.
I saw the example RPCdemo attached to errai-1.3.0.CR1.zip file and there is an example how to catch exceptions raised on server side, but it's for RPC calls only.
How can I catch server-side exceptions with using errai messages?
