DEPRECATION: ember-views.render-double-modify

[notmessenger]

DEPRECATION: You modified (-join-classes "ember-view" "ef-textarea" (-normalize-class "errorState" errorState activeClass="ef-error" inactiveClass=undefined)) twice in a single render. This was unreliable in Ember 1.x and will be removed in Ember 3.0 [deprecation id: ember-views.render-double-modify]

This was introduced by ember-forge/ember-forge-ui@1beda3f and 1a741b6

Further explanation is available at ember-forge/ember-forge-ui#152
