designer 5.1.0 beta issue with RPC interface generating

Postby colinzhao » Fri Jul 18, 2008 10:06 am

I have start the migration to GWT 1.5 and Designer 5.1.0 today and notificed an issue with Designer generating incorrect * interface when I have an RPC call in an interface returning a void. Pay attention to the testCall() method of the following sample code:

Service interface

Code: Select all
public interface TestService extends RemoteService {
    * Utility class for simplifying access to the instance of async service.
   public static class Util {
      private static TestServiceAsync instance;
      public static TestServiceAsync getInstance(){
         if (instance == null) {
            instance = (TestServiceAsync) GWT.create(TestService.class);
            ServiceDefTarget target = (ServiceDefTarget) instance;
            target.setServiceEntryPoint(GWT.getModuleBaseURL() + "TestService");
         return instance;
   public void testCall();

Designer generated the its Async interface as following:

Code: Select all
public interface TestServiceAsync {
   public void testCall(AsyncCallback<void> callback);

which causes a compiler error and need to be corrected with <Void> instead of <void>.
