My rendering class looks like below,

 public class Redirection : RenderingModel
    {
        [SitecoreField("Destination")]
        public virtual Glass.Mapper.Sc.Fields.Link Destination { get; set; }

        [SitecoreField("Type")]
        public virtual StatusCodes Type { get; set; }
    }

    public enum StatusCodes
    {
        Permanent = 301,
        Temporary = 302
    }

my controller method looks like,

public ActionResult Redirect()
        {
            var context = new SitecoreContext(IdpTemplates.CurrentContext);

            var redirection = context.GetCurrentItem<Redirection>();

            return new RedirectResult(redirection.Destination.Url, Convert.ToInt32(redirection.Type) == 301);
        }

in above method I am getting exception at var redirection = context.GetCurrentItem(); line.

Answer 1

Your fieldvalue contains 'PermanentRedirect' but your enum does not have that value. It has: 'Permanent' and 'Temporary'.

The names must have an exact match (case sensitive). Maybe you changed it at a certain point in time? Or maybe you have a wrong default value?
