Question

i am trying to make a table from 2 arrays in AngularJS one array contains Employees name and other array contain Services Name and rest of the cells contain check boxes but when i do i got error Error: [ngRepeat:dupes]
here is my AngularJS code
var model = angular.module('wizard', ['ngRoute'])
.config(["$routeProvider", function ($routeProvider) {
$routeProvider.when("/m5", {
controller: "model5Controller",
templateUrl: "/templates/m5.html"
});
$routeProvider.otherwise({ redirectTo: '/' });
}]);
var model5Controller = ["$scope", "$http", "$window", function ($scope,
$http, $window) {
$scope.PBA = [];
$scope.SOB = [];
$http.get('/Test/GetPBA').
then(
function (result) {
//success
$scope.PBA = result.data;
},
function () {
//error
});
$http.get('/Test/GetSOB').
then(
function (result) {
//success
$scope.SOB = result.data;
},
function () {
//error
});
$scope.save = function () {
//to be written
};
}];
GetPBA/GetSOB returns JSON type Array of List
both contain properties like Id, Name
here is my html
<div>
<form ng-submit="save()">
<table border="1">
<tr>
<td><strong>Services</strong></td>
<td ng-repeat="e in PBA">{{e.Name}}</td>
</td>
<tr ng-repeat="i in SOB">
<td>{{i.Name}}</td>
<td ng-repeat="e in PBA">
<input type="checkbox" name="{{e.Id}}" />
</td>
</tr>
</table>
</form>

Answer 1

Try this
<tr ng-repeat="i in SOB track by $index">
<td>{{i.Name}}</td>
<td ng-repeat="e in PBA track by $index">
<input type="checkbox" name="{{e.Id}}" />
</td>
</tr>
