When saving an entity, how one can change the position of notifications showing the validation errors?

Hello!

In this case, you should show your own notification.

Disable standard notification:

@Subscribe
public void onInit(final InitEvent event) {
    setShowValidationErrors(false);
}

And set fail handler to saveAction:

@Autowired
private Notifications notifications;

@Autowired
private Messages messages;

@Install(to = "saveAction", subject = "failHandler")
private void saveActionFailHandler() {
    ViewValidation viewValidation = getApplicationContext().getBean(ViewValidation.class);

    ValidationErrors validationErrors = viewValidation.validateUiComponents(getContent());
    String message = ViewValidation.getValidationErrorsMessage(validationErrors);

    notifications.create(messages.getMessage("validationFail.title"), message)
            .withPosition(Notification.Position.MIDDLE)
            .show();
}
