Fixed issue when typing or deleting really fast $apply already in progress Issue #84

[alastair-todd]

Hi I did some research, I think wrapping the $apply call would be better in a $timeout?

See:

 autocompleteService.getPlacePredictions(request, function(predictions, status) {
     $timeout(function() {

         $scope.$apply(function() {

             var customPlacePredictions;

             clearPredictions();

             if ($scope.customPlaces) {
                 customPlacePredictions = getCustomPlacePredictions($scope.query);
                 $scope.predictions.push.apply($scope.predictions, customPlacePredictions);
             }

             if (status == google.maps.places.PlacesServiceStatus.OK) {
                 $scope.predictions.push.apply($scope.predictions, predictions);
             }

             if ($scope.predictions.length > 5) {
                 $scope.predictions.length = 5; // trim predictions down to size
             }
         });
     });
 });
