Enum selection factory not working – what is the problem?

I need to use System.Net.Mail.MailPriority as enum on property. I have found many recepies how to do it but none of them worked.

Code:

public class EmailPrioritySelectionFactory : ISelectionFactory
{
  public IEnumerable  GetSelections(ExtendedMetadata metadata)
        {
            return new[]
            {
                new SelectItem { Text = "Low", Value = MailPriority.Low },
                new SelectItem { Text = "Normal", Value = MailPriority.Normal },
                new SelectItem { Text = "High", Value = MailPriority.High },
            };
        }
}

[EditorDescriptorRegistration(TargetType = typeof(MailPriority))]
public class EmailPriorityEditorDescriptor : EditorDescriptor
{
        public EmailPriorityEditorDescriptor()
        {
            SelectionFactoryType = typeof(Business.SelectionFactories.CustomerServicePage.EmailPrioritySelectionFactory);
            ClientEditingClass = "epi-cms/contentediting/editors/SelectionEditor";
            DefaultValue = MailPriority.Low;
        }
}

Issue is that default value from editor descriptor is not mapped in any case. It takes 0 – normal. I am affraid I have found bug.

On setting

[EditorDescriptor(EditorDescriptorType = typeof(EditorDescriptors.EmailPriorityEditorDescriptor))]
[BackingType(typeof(PropertyNumber))]
public virtual MailPriority Priority { get; set; }

or

[SelectOne(SelectionFactoryType = typeof(EmailPrioritySelectionFactory))]
[BackingType(typeof(PropertyNumber))]
public virtual MailPriority Priority { get; set; }

on value change I got (XHR) response from server

message: "Unable to load /EPiServer/cms/Stores/contentdata/35_75 status: 500"

response: Object { url: "/EPiServer/cms/Stores/contentdata/35_75", loaded: 9009, total: 9009, … }

Am I doing something wrong in order to setup this simple enum selection on model?

Hi Jiri,

The easy answer (probably) is to set it on your content type using:

public override void SetDefaultValues(ContentType contentType)
{
    base.SetDefaultValues(contentType);

    Priority = MailPriority.Low,
}

Do you have any reason not to use this approach?

Ah, ok.

In Admin > Content Type can you navigate to a content type that is using your Priority property. What type is it? I'm expecting integer from your code above.

It’s Long string :-( but you intention was right. Setting it to int fixed the problem. I spent with it some hours. Thank you.

Hitting the "Revert to Default" button should fix that -- if I remember correctly.
