Hi Telerik team,

We have an issue with image manager in the editor. When we refresh page or save image, it throws error message.

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.
     at Telerik.Web.UI.ImageEditor.ImageEditorCacheHandler.SendImage"


Please help us out.

Thanks,

Lan

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,
