<pre name="code" class="javascript">state("merchantProductEdit",{
url : "/merchantProductEdit/:viewType/:merchantProduct",
templateUrl : "module/merchantProduct/merchant_product_edit.html",
controller : "merchantProductEditController"
})

backuser.controller('merchantProductEditController', function($scope, $http, $stateParams, merchantProductEditService, merchantProductListService, fileReaderUtil, backUserUtil, ouser) {
$scope.viewType = $stateParams.viewType;
$scope.vm.id = $stateParams.merchantProduct;
$scope.uploadPdfDisabled = false;
