Hi All!

I've tried to use enum fields in my domain model. The documentation says, that it is allowed and supported.

(Modeling domains page: 1. The following field types are supported: sbyte, byte, short, ushort, int, uint, long, ulong; single, double, decimal; bool; string, char; DateTime, TimeSpan; Guid; enum; byte[]; Key; Descendants of Structure; Descendants of Entity; EntitySet<t>)

But Domain.Build(...) method throws an exception: "Literal type 'Model.EEntityLifeState' is not supported."

To be more precise... DO4 builds the domain without any exception when using in-memory provider, but throws the exception when using sqlexpress provider.

Part of my model:

[Serializable]
public class MyEntity : BaseBusinessEntity
{
    [Field(Nullable=false, DefaultValue=EEntityLifeState.Live)]
    public EEntityLifeState LifeState { get; set; }
}

[Serializable]
public enum EEntityLifeState
{
    Live, Deleted
}

}

Please someone make it clear, when and how can be used enums in the model, and when not!

Thanks!

Hi Peter and Alex!

you are right, the problem is with DefaultValue. I've commented out the DefaultValue, and the exception has gone away... :)

Alex, the stack trace: In the public available source code (on google code) I've checked the Xtensive.Sql.SqlValidator.EnsureLiteralTypeIsSupported(Type type) method, and it throws the exception, the code is fairly simple and self-explaining. :)
