Method callback is not fired after client simulation using ValidatedMethod


ValidatedMethod is using the returnStubValue option when calling a method, but it doesn’t seem to work for me. I would like to know what you think about it.

Here is my server side method:

export const updateName = new ValidatedMethod({
  name: 'travelers.updateName',
  validate: new SimpleSchema({
    travelerId: { type: String, regEx: SimpleSchema.RegEx.Id },
    newName: { type: String },
  run({ travelerId, newName }) {

    if (this.isSimulation) {
      return { finished: false };

    Travelers.update(travelerId, { $set: { name: newName } });

    return { finished: true };

This a simple method that updates a name property in my Travellers collection. Client side I immediately return an object { finished: false }. Server side I update my database then return an object { finished: true }

Here is my client side call:{
  travelerId: this.props.travelerId,
  newName: value,
}, (err, res) => {

I just call the method and console.log the result. Because I am using mdg:validated-method which uses the returnStubValue option, I guess my console should output finished: false, then finished: true. But it actually only output finished: true.

Is there something I don’t understand here?

Thank you and sorry if my english is not perfect.

I just created a github repo that reproduce my problem:

Feel free to clone and test it. You will get a button on homepage. When you click on it, the console log displays the return value with a 3 seconds delay, corresponding of the (simulated) latency between server and client. I should get the console.log immediatly.
