AngularJS: minifications breaks my directive - angularjs

Question

I use a directive to ask user for action confirmations in modals.
It works like a charm during development, but, after minification, it's broken.
This is the dreadful "$injector: unpr" error I get:
Error: [$injector:unpr] Unknown provider: aProvider <- a
...
I presume the problem is that $scope and $modalInstance are renamed, and should not be, but I don't know how to avoid this...
This is the directive code:
'use strict';
app.directive('reallyClick', ['$modal', function($modal) {
var modalInstanceCtrl = function ($scope, $modalInstance) {
$scope.ok = function () {
$modalInstance.close();
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};
return {
restrict: 'A',
scope: {
reallyClick: '&',
item: '='
},
link: function (scope, element, attrs) {
element.bind( 'click', function() {
var message = attrs.reallyMessage || 'Are you sure?';
var modalHtml = '<div class="modal-body">' + message + '</div>';
modalHtml += '<div class="modal-footer"><button class="btn btn-primary" ng-click="ok()">OK</button><button class="btn btn-warning" ng-click="cancel()">Cancel</button></div>';
var modalInstance = $modal.open({
template: modalHtml,
controller: modalInstanceCtrl
});
modalInstance.result.then(function () {
scope.reallyClick({item:scope.item}); // raise an error : $digest already in progress
}, function() {
// modal dismissed
});
});
}
};
}]);
I use it this way:
...
<td title="Delete customer">
<button
class="btn btn-primary glyphicon glyphicon-trash"
really-message="Are you really sure to remove customer <i>{{customer.name}}</i> ?" really-click="deleteCustomer(customerId)"
></button>
</td>
...
If it can be of any help, these are the modules I use during the build phase:
'auto_install',
'clean:dist',
'favicons',
'wiredep',
'useminPrepare',
'concurrent:dist',
'autoprefixer',
'concat',
'ngmin',
'copy:dist',
'cdnify',
'cssmin',
'uglify',
'filerev',
'usemin',
'htmlmin',
and these are the modules I inject in my app:
var app = angular.module('smallBusinessApp', [
'ngSanitize',
'ngRoute',
'firebase',
'ui.bootstrap',
]);

The modalInstance Controller needs to be created with the dependency injection syntax as well,
'use strict';
app.directive('reallyClick', ['$modal', function($modal) {
return {
restrict: 'A',
scope: {
reallyClick: '&',
item: '='
},
link: function (scope, element, attrs) {
element.bind( 'click', function() {
var message = attrs.reallyMessage || 'Are you sure?';
var modalHtml = '<div class="modal-body">' + message + '</div>';
modalHtml += '<div class="modal-footer"><button class="btn btn-primary" ng-click="ok()">OK</button><button class="btn btn-warning" ng-click="cancel()">Cancel</button></div>';
var modalInstance = $modal.open({
template: modalHtml,
controller: modalInstanceCtrl
});
modalInstance.result.then(function () {
scope.reallyClick({item:scope.item}); // raise an error : $digest already in progress
}, function() {
// modal dismissed
});
});
}
};
}]);
ModelInstanceController:
app.controller('modalInstanceCtrl',['$scope','$modalInstance',function ($scope, $modalInstance) {
$scope.ok = function () {
$modalInstance.close();
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
}]);
Was a problem for me too and had to separate the controller part of the modal and do it like this, hope it helps!!

I guess it's your modalInstanceCtrl. Try to not implement is as an object inside your directive, but as a controller:
app.controller('modalInstanceCtrl', [ '$scope', '$modalInstance',
function ($scope, $modalInstance) {
$scope.ok = function () {
$modalInstance.close();
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
}]);
And lateron reference it by putting it in quotes:
var modalInstance = $modal.open({
template: modalHtml,
controller: 'modalInstanceCtrl'
});
