dependency injection - MVP GWT - problem injecting EventBus -

weird problem, when inject eventbus e got exception. project gwt using mvp

here sample code.

gin

public interface appginjector extends ginjector {   eventbus geteventbus();   placemanager getplacemanager(); } 

here entry point

public class mvpentrypoint implements entrypoint { appginjector ginjector = gwt.create(appginjector.class);  public void onmoduleload() {    eventbus eventbus = ginjector.geeventbus();   helloworldpanel display = new helloworldpanel();   helloworldpresenter presenter = new helloworldpresenter( display, eventbus );    presenter.bind();    rootpanel.get().add( presenter.getdisplay().aswidget() );    placemanager placemanager =  ginjector.getplacemanager();   placemanager.firecurrentplace();  } 

i use gin 1.0 , gwt-presenter

any has idea?

thanks

edit:

the exception is

error: deferred binding result type 'net.customware.gwt.presenter.client.eventbus' should not abstract.  error: unable load module entry point class com.gmgsys.mvpentrypoint.client.mvpentrypoint (see associated exception details). java.lang.runtimeexception: deferred binding failed 'net.customware.gwt.presenter.client.eventbus' (did forget inherit required module?) ........................... 

also gwt.xml

  <!-- specify app entry point class.                   -->     <entry-point class='com.gmgsys.mvpentrypoint.client.mvpentrypoint'/>     <inherits name='net.customware.gwt.presenter.presenter' />     <inherits name="com.google.gwt.inject.inject" /> 

i think missing abstractpresentermodule class makes sure eventbus bound simpleeventbus:

bind(eventbus.class).to(simpleeventbus.class).in(singleton.class); 

it should that:

public class myclientmodule extends abstractpresentermodule {   protected void configure() {      bind(eventbus.class).to(simpleeventbus.class).in(singleton.class);      // more bindings here   } } 

and have annotate ginjector

@ginmodules({ myclientmodule .class }) public interface appginjector extends ginjector {   eventbus geteventbus();   placemanager getplacemanager(); }
