Angularjs $http.get().then and binding to a list

$http methods return a promise, which can’t be iterated, so you have to attach the results to the scope variable through the callbacks:

$scope.documents = [];
$http.get('/Documents/DocumentsList/' + caseId)
  .then(function(result) {
    $scope.documents = result.data;
});

Now, since this defines the documents variable only after the results are fetched, you need to initialise the documents variable on scope beforehand: $scope.documents = []. Otherwise, your ng-repeat will choke.

This way, ng-repeat will first return an empty list, because documents array is empty at first, but as soon as results are received, ng-repeat will run again because the `documents“have changed in the success callback.

Also, you might want to alter you ng-repeat expression to:

<li ng-repeat="document in documents" ng-class="IsFiltered(document.Filtered)">

because if your DisplayDocuments() function is making a call to the server, than this call will be executed many times over, due to the $digest cycles.
