@GenEvent tag doesn't manage generic event

[Veknelyon]

Generic event class are not well generated with GenEvent tag.

Example :

import com.gwtplatform.dispatch.annotation.GenEvent;

@GenEvent
public class Save<T> {
    private T savedObject;
}

Generate not compilable class SaveEvent (because Class and static methods are not generic) :

import com.google.gwt.event.shared.EventHandler;
import com.google.gwt.event.shared.GwtEvent;
import com.google.web.bindery.event.shared.HandlerRegistration;

import com.google.gwt.event.shared.HasHandlers;

public class SaveEvent extends GwtEvent<SaveEvent.SaveHandler> {

  private T savedObject;

  protected SaveEvent() {
    // Possibly for serialization.
  }

  public SaveEvent(T savedObject) {
    this.savedObject = savedObject;
  }

  public static void fire(HasHandlers source, T savedObject) {
    SaveEvent eventInstance = new SaveEvent(savedObject);
    source.fireEvent(eventInstance);
  }

  public static void fire(HasHandlers source, SaveEvent eventInstance) {
    source.fireEvent(eventInstance);
  }

  public interface HasSaveHandlers extends HasHandlers {
    HandlerRegistration addSaveHandler(SaveHandler handler);
  }

  public interface SaveHandler extends EventHandler {
    public void onSave(SaveEvent event);
  }

  private static final Type<SaveHandler> TYPE = new Type<SaveHandler>();

  public static Type<SaveHandler> getType() {
    return TYPE;
  }

  @Override
  public Type<SaveHandler> getAssociatedType() {
    return TYPE;
  }

  @Override
  protected void dispatch(SaveHandler handler) {
    handler.onSave(this);
  }

  public T getSavedObject(){
    return savedObject;
  }

  @Override
  public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    SaveEvent other = (SaveEvent) obj;
    if (savedObject == null) {
      if (other.savedObject != null)
        return false;
    } else if (!savedObject.equals(other.savedObject))
      return false;
    return true;
  }

  @Override
  public int hashCode() {
    int hashCode = 23;
    hashCode = (hashCode * 37) + (savedObject == null ? 1 : savedObject.hashCode());
    return hashCode;
  }

  @Override
  public String toString() {
    return "SaveEvent["
                 + savedObject
    + "]";
  }
}
