    Details :

    1. we use Web Farm
    2. telerik product version : 2012.1.411.40
    3. the issue is not browser specific
    4. random happens but not always
    5. error message ( please see the attachment )
        "System.NullReferenceException: Object reference not set to an instance of an object.

    Hi Lan,

    The RadControls for ASP.NET AJAX have no issues if the webfarm is configured with a sticky session or if a state server is used to share the session between web servers. Please, make sure that you are using one of both options in your webfarm to ensure seamless operation of RadImageEditor.

    Best regards,
    the Telerik team
