We've developed a web app with Asp.Net MVC 3 using Razor pages.
In the page we're having problems with a user selects items from a menu and they're added to the order details pane on the right of the page, where multiple items of the same type are totaled up e.g. 3 x Garlic Bread etc.
To do this we add to a list of T and store it in a session variable as in the following code:
List<MunuItems> OrderItems = HttpContext.Session["_OrderItems"] as List<MunuItems>;
MunuItems newItem = new MunuItems();
// Set the newItem values
OrderItems.Add(newItem);
// Add the list to the session
HttpContext.Session.Add("_OrderItems", OrderItems);
// Retrun the partial view
return PartialView("_OrderItems", OrderItems);
This all works fine in Firefox or Chrome, but when I try this in Internet Explorer 8 / 9 the behavior is all over the place. Only 1 of each item can be added, trying to add 2nd items can cause other items to drop off the list etc.

Can anyone suggest how this can be fixed in Internet Explorer or why it's not working in IE?
