javascript - Angular UI Router resolve throwing provider error -

i seem having issue angular ui router , trying add resolve state. weird thing is, have in place , works fine.

i'm separating code out different component areas, code structure this:

/app   /component-dashboard     index.js     /controllers       dashboardctrl.js   /component-chart-1     index.js     /controllers       chart1ctrl.js 

for example have root dashboard , works fine:

// index.js  angular.module('az-ci') .config([   '$stateprovider',   function($stateprovider) {      $stateprovider       .state('dashboard', {         templateurl: '/app/ci-dashboard/templates/dashboard.html',         url: '/',         controller: 'dashboardctrl',         resolve: {           chartlist: function() {             return [{               name: 'chart 1',               state: 'dashboard.chart1'             }];           }         }       });   } ]);  // dashboard ctrl angular.module('az-ci') .controller('dashboardctrl', [   '$scope',   '$rootscope',   'chartlist',   function($scope, $rootscope, chartlist) {      $scope.chartlist = chartlist;    } ]); 

however in chart component, following error (simplified) code:

// error error: [$injector:unpr] unknown provider: productlistprovider <- productlist  // index.js angular.module('az-ci') .config([   '$stateprovider',   function($stateprovider) {      $stateprovider       .state('dashboard.chart1', {         templateurl: '/app/ci-chart-1/templates/chart.html',         url: '/chart/chart1',         controller: 'chart1ctrl',         resolve: {           productlist: ['csv', '$stateparams', function(csv, $stateparams) {             return {};           }]         }       });   } ]);  // chart1ctrl angular.module('az-ci') .controller('chart1ctrl', [   '$scope',   '$rootscope',   '$state',   'productlist',   function($scope, $rootscope, $state, productlist) {      $scope.products = productlist;    } ]); 

the problem had defined controller used in directive created display d3 chart. removing defined controller fixed it.
