Adding multiple expressions using ng-class in AngularJS

I am trying to set the class .active when the path is http://localhost/#/ or http://localhost/#/main/ as both paths are the same page.

Why does ng-class="{'class1' : expression1, 'class1' : expression2}" not work?

Controller

angular.module('testApp')
  .controller('NavmenuCtrl', function ($scope, $location) {
  $scope.isActive = function (providedPath) {
    return providedPath === $location.path();
  };
});

Partials View

<li ng-class="{ active: isActive('/'), active: isActive('/main/')}">
  <a href="#/">Home</a>
</li>

Day late but hopefully worth something.

You could also write it using the or operator for one instance of the class.

ng-class="{ 'active': condition1 || condition2 }"

Making my comment an answer, Yes your issue is with the duplicate keys, you could just do:-

ng-class="{ active: isActive('/') || isActive('/main/')}"

Or probably better:-

Let your isActive class accept multiple arguments:-

$scope.isActive = function () {
    //Look for a match in the arguments array
    return [].indexOf.call(arguments, location.path()) > -1;
};

and use it as:-

ng-class="{ active: isActive('/', '/main/')}"

Shim support for indexOf for older browsers
