Throwing an empty server-side exception results in raising a client-side "TypeError: resultObj is undefined" error

created 9 years ago

In the most common scenario, a control can handle server-side exceptions. For example, the MVC Scheduler control renders an exception's message in its markup.
The MVC GridView control displays the exception's message in the "alert" window.
However, when the exception contains an empty message, a client-side "TypeError: resultObj is undefined" error is raised and a current callback request can't be completed.
In the attachment, you can find a sample project and a video which illustrates how to reproduce the issue.
