Validation not called on server side

[DarthRumata]

We have strange issue with our custom validator that checking unique field of Model. If there are other errors while validation custom validator doesn't launched at server(only on client in simulation). If we have no other validation errors so it launches on server and everything is ok.

How simulation should work? Does it start every time or there is some important condition?

Our validator:

Validator.create({
  name: 'unique',
  isValid({name, value, doc}) {
    const collection = doc.constructor.getCollection();
    let selector = {};
    selector[name] = value;
    console.log(selector);
    const foundItems = collection.find(selector);

    const count = foundItems.count();
    if (count > 1) {
      return false;
    }
    if (count === 0) {
      return true;
    }
    const foundItem = foundItems.fetch()[0];
    return foundItem._id === doc._id;
  },
  resolveError() {
    return 'uniqueViolationError';
  }
});

Our validated Model:

const InitiatorFormData = CompanyFormData.inherit({
  name: 'InitiatorFormData',
  fields: {
    identifier: {
      type: String,
      default: '',
      validators: [
        {type: 'unique'},
        {
          type: 'length',
          param: 8,
          message: 'lengthError',
        },
      ],
    },
    kind: {
      type: InitiatorKind,
      default: InitiatorKind.GENERAL,
    },
  },
  helpers: {
    getFieldNames() {
      return ['identifier', 'shortName', 'fullName', 'address', 'mainActivity', 'webSite', 'kind'];
    },
  },
});

and base Model:

const CompanyFormData = Class.create({
  name: 'CompanyFormData',
  typeField: 'type',
  collection: Companies,
  fields: {
    shortName: {
      type: String,
      default: '',
      validators: [{type: 'notEmpty'}],
    },
    fullName: {
      type: String,
      default: '',
      validators: [{type: 'notEmpty'}],
    },
    address: {
      type: Address,
      default: new Address(),
    },
    mainActivity: {
      type: String,
      default: '',
      validators: [{type: 'notEmpty'}],
    },
    webSite: {
      type: String,
      default: '',
      optional: true,
      validators: [{type: 'isValidWebUri'}],
    },
  },
});

P.S.: As temporary solution I disabled simulation and it allowed this validator work all the time.

Have you tried setting the stopOnFirstError flag to false? It's described in docs http://jagi.github.io/meteor-astronomy/v2#validation

[DarthRumata]

Yes. It is always set to false. We have many form validations.
"company.validate({stopOnFirstError: false}, ..."

So, you have to create reproduction repository. Without that it's hard to tell
