We have noticed that when a user has a period of inactivity and their session times out, when they click a link/action/try to do something they are presented with a modal popup and an error like this:
Error in: /SomeRepository/Action/GetAllClaims?id=Namespace.SomeRepository%3B1%3BSystem.Int32%3B0%3BFalse%3B%3B0 error:""
If the user refreshes the page, they are redirected to the login page. Once they login, they can continue without any problems.
I'm wondering if this is a limitation with the the AJAX architecture whereby it is not possible to redirect the page to a URL from an AJAX request?
