I was testing upgrading a website from 10.3.2 to 10.4 and have found that some of my backoffice custom controllers are no longer working.

Basically anywhere which calls $rootScope.$broadcast('event_name', { data: 'xxx' }) to pass data to sub controls no longer seems to work when used in umb-editor-view / umb-editor-sub-views.

On upgrading to 11.1 it is the same.

In parent controller:

$rootScope.$broadcast('user_init', {
  user: myUser
});

In child controller - never triggers

$scope.$on("user_init", function (evt, model) {
  vm.user = model.user;
}

Its probably not how data should be passed between controllers in editor view but anyone know why or able to give example of the correct way?
