[v2] Exception while invoking mfStrings/insert: no translations get saved

[ttasovac]

Hi.

I'm using the latest v2 previews:

msgfmt:core@2.0.0-preview.15 (2015-12-23) msgfmt:extract@2.0.0-preview.12 msgfmt:ui@2.0.0-preview.5

I have created some strings in the appropriate {{mf}} format and msgfmt:extract has recognized them automatically. However, when I create a new language in the UI, and when I translate the strings, they do not get saved. Instead, I am getting this:

I20160105-07:12:20.904(1)? Exception while invoking method '/mfStrings/insert' Error: Meteor.userId can only be invoked in method calls. Use this.userId in publish functions.

This happens regardless of whether I am logged in or not.

All best, Toma
