MVC Beta [HandleError] Attribute (need help)

Question

I've tried this both with and without the 'ExceptionType' parameter. I have an Error.aspx page in both the Views/Shared folder and the Views/thisController folder. But everytime I run this I get a "Server Error in '/' Application." error page, rather than the nice one in Views/Shared.

Any idea what could be going wrong here?

[HandleError(View="Error",ExceptionType=typeof(FormatException))]

    public ActionResult Create()
    {
        throw new Exception();
        //int breakMe = int.Parse("not a number");
        return View();
    }

Answer 1

I'm getting the same issue as we speak. I can get it working on a new MVC Application but not my existing one.

Weird

Answer 2

It doesn't work for me on my current project or a new one. It's probably a "feature".

EDIT: it looks like you have customErrors enabled (mode="On") for it to work according to this snippet from HandleErrorAttribute.cs:

// If custom errors are disabled, we need to let the normal ASP.NET exception handler
// execute so that the user can see useful debugging information.
if (filterContext.ExceptionHandled || !filterContext.HttpContext.IsCustomErrorEnabled) {
  return;
}

Answer 3

I do indeed have this in my web.config

<customErrors mode="On"></customErrors>

Must be something else at play.

Answer 4

Good call guys, once I changed the customErrors mode property from 'remoteOnly' to 'On' it did indeed start working! Thanks!

Answer 5

I'm having problems with this too, and I can't get it to work on my local workstation when just opening a new ASP.NET MVC Application template project, adding the HandleError attribute to the Index controller and the following line to the Index method:

throw new ApplicationException("oops...");

I get the standard ASP.Net Error Page.
