$scope.save = function() {     if (dosubmit) {         var dto = {             'attributes': $scope.fields,             'requestorigin': $location.absurl()         };         var req = {             method: 'post',             url: 'endpoint',             data: dto         };         $http(req).success(function(data, status) {             // success             $scope.completed(data);         }).error(function(data, status) {             // error_1             $scope.validationfailed();         });      } else {         // error_2         $scope.validationfailed();     } } // used provide error messages input validation $scope.validationfailed = function(message, id) {     $scope.alerts.push({          type: 'danger',          msg: message || 'error.validation_failed', id: id || 'general'     }); } 

i read case somewhere can't remember source. link or short elaboration helpful.

addition 1 $scope.validationfailed

my comment answer:

maybe it's $http error callback $scope.validationfailed(); executed? try adding alert(1); in error callback.

this might indicate server side problem, causing server return status code different 200 both else statement , error callback executing same function, show else statement not 1 being executed.
