Hello,

In the file addons/web/static/src/js/view.js

replace this code :

var titles = _.map(views, function(v) { var controller = self.views[v].controller; if (v === 'form') { id = controller.datarecord.id; } return controller.get('title'); });

by this code :

var titles = _.map(views, function(v) { if (self.views[v]) { var controller = self.views[v].controller; if (v === 'form') { id = controller.datarecord.id; } return controller.get('title'); } });

Try it please and answer. Thanks.
