Hi there!!
I have a problem to view my selected Task in ionic but in my web app it works perfectly because i have list of task in the right and when i clicked specific task it display the selected Task in the left side
but in ionic i create another view for specific task and i get the id in the url but the data not display..!!

This is my code ...

browseDetailCtrl.js

app.controller('browseDetailCtrl', function($scope,$ionicPopup, $stateParams, Auth,Task) {

$scope.tasks = Task.all;

$scope.user = Auth.user;
$scope.signedIn = Auth.signedIn;

if($stateParams.taskId) {
var task = Task.getTask($stateParams.taskId).$asObject();
setSelectedTask(task);
}

function setSelectedTask(task) {
$scope.selectedTask = task;
};

routes.js

.state('tabsController.browse', {
url: '/browse',
views: {
'tab1': {
templateUrl: 'templates/browse.html',
controller: 'browseCtrl'
}
}
})

.state('tabsController.browseDetail', {
  url: '/browseDetail/:taskId',
  views: {
    'tab1': {
      templateUrl:'templates/browseDetail.html',
      controller: function($stateParams){
        $stateParams.id;
      }
    }
  }
})

service

app.factory('Task', function(FURL,$firebaseObject,$firebaseArray, Auth) {
var ref = new Firebase(FURL);
var tasks = $firebaseArray(ref.child('tasks'));
var user = Auth.user;

var Task = {
all: tasks,

getTask: function (taskId) {
  return $firebaseObject(ref.child('tasks').child(taskId));
},

createTask: function (task) {
  task.datetime = Firebase.ServerValue.TIMESTAMP;
  return tasks.$add(task)
    .then(function(newTask) {
      // Create User-Tasks lookup record for POSTER
      var obj = {
        taskId: newTask.key(),
        type: true,
        title: task.title
      };

      return $firebaseObject(ref.child('user_tasks').child(task.poster)).$push(obj);
    });
},
