This doesn't answer your question directly but it should give you some
ideas:
public abstract class ActionCallback<ResultType> implements
AsyncCallback<ResultType> {
@Override
public final void onFailure(Throwable caught) {
BusyIcon.hide();
Window.alert("RPC Error: " + caught.getMessage());
handleFailure(caught);
}
@Override
public final void onSuccess(ResultType result) {
BusyIcon.hide();
handleSuccess(result);
}
/* Override to handle event failure result */
protected abstract void handleFailure(Throwable caught);
/* Override to handle event success result */
protected abstract void handleSuccess(ResultType result);
}
