Scheduler Sends Multiple Create, Destroy, or Update Requests to the Remote Service

Environment

Product	Progress® Kendo UI® Scheduler for jQuery
Operating System	Windows 10 64bit

Description

While working with the jQuery Scheduler, a create/destroy/update request is sent multiple times to the remote service.

Cause

In this case the server response of the create/destroy/update action is interpreted as an error by the dataSource and the error event of the dataSource is triggered. When such a request fails, the Scheduler dataSource will try to get a valid server response again on a subsequent dataSource sync until the request succeeds.

Solution

Update the remote service in use, so it can return valid responses. Make sure the server response is formatted in the same way as the read action response:

1. The create request—The Scheduler expects the created record to be returned to the client side with its id field set to a unique value.
2. The update/destroy request—The Scheduler expects the server to return a valid response, so it can signify success. Such a response, for example, is the updated/deleted event formatted in the same way as the read action [{id: 23, title: "some title", start:"2015-10-14T15:00:00.000Z", end:"2015-10-14T17:00:00.000Z" }].
