Answer by Ciul for AngularJS : Prevent error $digest already in progress when calling $scope.$apply()

I had the same problem with third parties scripts like CodeMirror for example and Krpano, and even using safeApply methods mentioned here haven't solved the error for me.

But what do has solved it is using $timeout service (don't forget to inject it first).

Thus, something like:

$timeout(function() {
  // run my code safely here
})

and if inside your code you are using

this

perhaps because it's inside a factory directive's controller or just need some kind of binding, then you would do something like:

.factory('myClass', [
  '$timeout',
  function($timeout) {

    var myClass = function() {};

    myClass.prototype.surprise = function() {
      // Do something suprising! :D
    };

    myClass.prototype.beAmazing = function() {
      // Here 'this' referes to the current instance of myClass

      $timeout(angular.bind(this, function() {
          // Run my code safely here and this is not undefined but
          // the same as outside of this anonymous function
          this.surprise();
       }));
    }

    return new myClass();

  }]
)
