Inject into anonymous inner class (GIN) - gwt

Question

I have something like this:
request.findAllProjects().fire(new ExtReceiver<List<ProjectProxy>>() {
#Override
public void onSuccess(List<ProjectProxy> response) {
view.setProjects(response);
}
});
It is anonymous inner class of the abstract class ExtReceiver. The ExtReceiver is for handling the errors with an errorHandler which i want to provide.
public abstract class ExtReceiver<T> extends Receiver<T> {
private ErrorHandler errorHandler;
public ExtReceiver() {
}
#Inject
public void setErrorHandler(ErrorHandler errorHandler)
{
this.errorHandler = errorHandler;
}
#Override
public abstract void onSuccess(T response);
#Override
public void onFailure(ServerFailure error) {
errorHandler.exception(error);
}
#Override
public void onViolation(Set<Violation> errors) {
ValidationUtils.processViolation(errors);
}
}
I understand why this can't work, because i use the new Operator. But how could i do something like this. I want to have that anonymous class and not put it in an own file or something.
How could I inject that errorHandler? Thought about staticInjections, but it looked like this does not work too (Maybe because of the inheritance i create with doing an anonymous class)
In the opposite to normal Guice i don't know an injector.getInstance() call.
For information: That is a requestFactory call

Why don't you put the errorHandler parameter into the constructor of your abstract class instead creating a separate setErrorHandler setter, something like this:
public abstract class ExtReceiver<T> extends Receiver<T> {
private ErrorHandler errorHandler;
#Inject
public ExtReceiver(ErrorHandler errorHandler) {
this.errorHandler = errorHandler;
}
}
Declare the bindings:
public class MyClientModule extends AbstractGinModule {
protected void configure() {
bind(ErrorHandler.class).in(Singleton.class);
}
}
Declare a Ginjector for your ErrorHandler class annotating it with the Module:
#GinModules(MyClientModule.class)
public interface MyErrorHandlerInjector extends Ginjector {
ErrorHandler getErrorHandler();
}
and then use it like this:
MyErrorHandlerGinjector injector = GWT.create(MyErrorHandlerGinjector.class);
ErrorHandler errorHandler = injector.getErrorHandler();
request.findAllProjects().fire(new ExtReceiver<List<ProjectProxy>>(errorHandler) {
#Override
public void onSuccess(List<ProjectProxy> response) {
view.setProjects(response);
}
});
I think this should work.
