    "There are no proxy providers registered yet" on first load of Form

    Thomas Frühbeck Newbie

      When  I access my Form directly via URL the first time e.g. Browser refresh on http://localhost:8080/aero2/index.jsp?gwt.codesvr=127.0.0.1:9997#ChildForm

      I always get the following error, on any subsequent access to the form e.g. via @Page reference, it works OK:

       

      00:12:04,438 [ERROR] ParentService:

      java.lang.RuntimeException: There are no proxy providers registered yet.     at org.jboss.errai.bus.client.framework.RemoteServiceProxyFactory.getRemoteProxy(RemoteServiceProxyFactory.java:37)     at org.jboss.errai.ioc.client.api.builtin.CallerProvider$1.call(CallerProvider.java:51)     at at.tfr.aero2.client.ChildForm.init(ChildForm.java:93)

       

      this is a sample of the code

       

         @Inject

         @DataField

         private ListBox parents;

       

         @PostConstruct

         public void init() {

            try {

               GWT.log("calling parentService");

               parentService.call(

                       new RemoteCallback<List<WrappedParent>>() {

                          @Override

                          public void callback(List<WrappedParent> response) {

                             GWT.log("found Parents: "+response);

                             ChildForm.this.loadParents(response);

                          }

                       },

                       new ErrorCallback() {

                          @Override

                          public boolean error(Message message, Throwable throwable) {

                             GWT.log("ParentService: ", throwable);

                             Window.alert(message.toString());

                             return false;

                          }

                       }).getAll();

            } catch (Exception e) {

               GWT.log("ParentService: ", e);

            }

         }

       

         public void loadParents(List<WrappedParent> parentSet) {

            GWT.log("loadParents: "+parentSet.size());

            for (WrappedParent p : parentSet) {

               parents.addItem(p.toString(), p.getId().toString());

            }

            parents.setVisible(true);

            parents.setVisibleItemCount(1);

         }

       

      Errai Version 2.2.0.CR2

       

      Thanks,
