Hello,

I am developing a custom payment provider, but I have some problems populating $scope.dialogData.provider.extendedData.items, which means that I cannot save/get any custom settings.

I have been looking at the implementation of different payment providers (braintree, quickpay, sage), but as I am fairly new to angularjs, I find it difficult to wrap my head around.

My two javascript files look like this:

payment.epay.module.js:

(function () {
    angular.module('merchello.plugins.epay', [
        'merchello.models',
        'merchello.services',
        'merchello.providers.models',
        'merchello.providers.directives',
        'merchello.providers.resources'
    ]);

    angular.module('merchello.providers.models', []);
    angular.module('merchello.providers.directives', []);
    angular.module('merchello.providers.resources', ['merchello.providers.models']);
    angular.module('merchello.plugins').requires.push('merchello.plugins.epay');
}());

payment.epay.providersettings.controller.js:

angular.module("merchello.plugins.epay")
    .controller("Merchello.Providers.Dialogs.EPayProviderSettingsController", ["$scope",
        function ($scope) {
            $scope.init = function () {
                if ($scope.dialogData.provider.extendedData.items.length > 0) {
                    var settingsString = items[0].value;
                    $scope.epaySettings = JSON.parse(settingsString);
                }

                $scope.$watch(function () {
                    return $scope.epaySettings;
                }, function (newValue, oldValue) {
                    $scope.dialogData.provider.extendedData.items[0].value = angular.toJson(newValue);
                }, true);
            };
            $scope.init();
        }
    ]);

In my controller I get an error when I try to access the first element of extendedData.items, which occurs when I click the 'edit' button on the providers page in the backoffice.

Can anybody tell me what I might be missing here, and how exactly is data transferred between my C# models/methods and angular modules?
