No Error Message showed for async validation triggered manually

[tonprince]

I am using the async custom validator on an input which is triggered manually:

$.formUtils.addAsyncValidator({
    loadHotelsByProduct(trip, function(hotels) {
      done(hotels.indexOf(value) != -1);
    });
  });

 pickupHotelNode.validate(function(valid, elem) {
 });

The problem is that there is no error message showed after the done callback is invoked, even the validation result is false.

My workaround is to call validateInputOnBlur explicitly after done call.

loadHotelsByProduct(trip, function(hotels) {
  done(hotels.indexOf(value) != -1);
  $input.validateInputOnBlur($.formUtils.LANG, $('form.booking').get(0).validationConfig, true);
});
