var app = angular.module('plunker', ['ui.router']);  app.config(['$stateprovider', function($stateprovider){   $stateprovider     .state('posts', {       url: "/posts",       templateurl: "posts-index.html",       controller: "postsindexcontroller",       resolve: {         posts: function(post) {           console.log('hi');           return post.all()         }       },       onenter: function($state, posts) {         if (posts.length > 1 && confirm("redirect first post?")) {           console.log('howdy')           // $state.go('posts.show', { postid: 3 });         }       }     })     .state('posts.empty', {       templateurl: "posts-show.html",       resolve: {         saysomething: function($state) {           console.log('yo')         }       }     })     .state('posts.show', {       url: "/:postid",       templateurl: "posts-show.html",       controller: "postsshowcontroller",       resolve: {         post: function($stateparams, $q, post) {           console.log($stateparams);           return post.find($stateparams.postid)         }       },       onenter: function($stateparams, $state) {         if ($stateparams.postid === '1') {           console.log('now')           return $state.go("posts.empty")         }       }     }) }]);  app.controller("postsindexcontroller", function($scope, posts){   $scope.posts = posts })  app.controller("postsshowcontroller", function($scope, post){   $scope.post = post })  app.run(function($rootscope, $state) {   $rootscope.$on('$statechangeerror', function(evt, to, toparams, from, fromparams, error) {     console.log(to, toparams)     console.log(from, fromparams)     if (error.redirectto) {       $state.transitionto(error.redirectto, error.redirecttoparams);     } else {       // $state.go('error', {status: error.status})     }   }) })  app.factory('post', function(){   return {     all: function() {       return [         { id: 1, title: "post 1" },          { id: 2, title: "post 2" },         { id: 3, title: "post 3" }       ]     },      find: function(id) {       return _(this.all()).findwhere({id: +id})     }   } })

i wrote comment, went bathroom , thought more.

since there's no way resolve, suggestion (and solution i'm using after trying it) controller, instead of rejecting resolve , trying handle $statechangeerror, resolve "redirect" child state , perform actual redirection child controller.

yes, it's ugly works.
