Angularfire error : Firebase Object is not a function

Question

I'm using angularfire to make a website but I'm not able to initialize firebase object in a controller. Here's my code

angular.module('displayApp').controller("ProductCtrl", function($scope, $firebaseObject,ProductDisplay) {
    this.products = ProductDisplay;

});

angular.module('displayApp').controller('descriptionCtrl', ['ProductDisplay','$stateParams','$firebaseObject',function (ProductDisplay,$firebaseObject,$stateParams) {
    var pid = 'productid1'
    var ref = new Firebase("https://bargainhawk.firebaseio.com/productDisplay/productid1");
    this.product =$firebaseObject(ref);

}])

This is my app.js file

  var displayApp= angular.module('displayApp', ["firebase",'ui.router']);

    displayApp.value("DB_URL","https://bargainhawk.firebaseio.com/productDisplay");

    displayApp.config(['$stateProvider', '$urlRouterProvider', function ($stateProvider,$urlRouterProvider) {
        $urlRouterProvider.otherwise("/");

        $stateProvider
        .state('home',
        {
            url:"/",
            templateUrl:"app/views/user/product-grid.html",
            controller:"ProductCtrl as collection"
        })
        .state('description',{
                url:'/product/{pid}',
            templateUrl:'app/views/user/description.html',
            controller:'descriptionCtrl as description'
        })  
        .state('description.chat',{
            url:'/chat',
            templateUrl:'app/views/user/chatWindow.html',

        })
    }])

Here's my factories file

angular.module('displayApp').factory("ProductDisplay", ["$firebaseObject","DB_URL",
    function ($firebaseObject,DB_URL) {
        var ref = new Firebase(DB_URL);
        return $firebaseObject(ref);    
    }])

The productCtrl is working but the descriptionCtrl is not. I can't find the mistake I'm making. I've tried the following code also

angular.module('displayApp').controller('descriptionCtrl', ['ProductDisplay','$stateParams','$firebaseObject',function (ProductDisplay,$firebaseObject,$stateParams) {
    var products = ProductDisplay;
    this.product = productDisplay.productid1;
    console.log(ProductDisplay);
    console.log(product);
}])

ProductDisplay Object is shown as it is at console but product is shown as undefined though the ProductDisplay has productid1 property.

Well if you check your descriptionCtrl you will find that the order of the params(dependencies) passed is not right

you typed :

angular.module('displayApp').controller('descriptionCtrl', ['ProductDisplay','$stateParams','$firebaseObject',function (ProductDisplay,$firebaseObject,$stateParams) {
    //...
}])

What you should have typed is :

angular.module('displayApp').controller('descriptionCtrl', ['ProductDisplay','$stateParams','$firebaseObject',function (ProductDisplay,$stateParams,$firebaseObject) {

}])

change the position of $firebaseObject with $stateParams

hope this will fix your problem

Happy coding :)
