Can't make "Asynchronous Custom Validation on the Client" to work

[qnreck]

I tried to use "Asynchronous Custom Validation on the Client" with my project, but it always fail for finding my server method on client side

attachmentIds: { type: Array }, 'attachmentIds.$': { type: String, custom: function () { if (Meteor.isClient && this.isSet) { Meteor.call("searchAttachment", { name: 'att1' }, (err, res) => { console.log("RESULT att::", this.value, err, res); // do smth }); } else { return Attachments.find(this.value).count() ? null : 'invalid'; } } }

With above code, result of Meteor.call('searchAttachment', ....) always undefined, and that searchAttachment method never run. Put that coded out of IF clause and it will works. I don't know if it is the correct way to use it or not. Please help. Thanks.

Meteor: 1.4.4.1
