Transformer returns null for read only properties

[Steven Roberts]

I have this Transformer

    public class TraceabilityTransformer : AbstractTransformerCreationTask<ProjectTraceability4>

    {

        public TraceabilityTransformer()

        {

            TransformResults = traceabilities => from traceability in traceabilities

                let roots = LoadDocument<IAmTraceable>(traceability.Connections.Select(x => x.Id))

                select new ProjectTraceabilityViewModel2

                {

                    Id = traceability.ProjectId,

                    Traceables = roots.Select(r => new RelatedTraceableViewModel

                    {

                        Id = r.Id,

                        Title = r.Name,

                        DeliverableId = r.DeliverableId,

                        Group = r.Group,

                        Status = r.CurrentStatus,

                        Type = r.Type,

                        Connections = traceability.Connections

                            .Where(x => x.Id == r.Id)

                            .ToDictionary(x => x.Id, x => x.Links.ToArray())

                    }).ToArray(),

                };

        }

    }

I'm using the interface (IAmTraceable) because the objects are different.  Everything works great except for the 2 properties that are read only. CurrentStatus and Type, both of which return hardcoded values as a Get only property.  I realize there are no 'types' on the server but without the IAmTraceable how do I get to use the properties that I need?

What are the properties that you have on the _document_? And how does the trasnformer looks on the server?

I realized shortly after posting and going to bed that the property naturally wouldn't exist on the server because it's a readonly get that isn't serialized.  I was able to solve for 1 of the properties by using metadata, but not the second.  The issue is that the documents that implement the interface have a property called Status, but the return type for each is different.  Here is the transformer on the server side that does work

from traceability in results

select new {

traceability = traceability,

roots = this.LoadDocument(traceability.Connections.Select(x => x.Id))

} into this0

select new {

Id = this0.traceability.ProjectId,

Traceables = Enumerable.ToArray(this0.roots.Select(r => new {

r = r,

metadata = r["@metadata"]

}).Select(this00 => new {

Id = this00.r.Id,

Title = this00.r.Name,

DeliverableId = this00.r.DeliverableId,

Group = this00.r.Group,

Status = this00.r.Status.State,

Type = this00.metadata.Value<string>("Raven-Entity-Name"),

Connections = Enumerable.ToDictionary(this0.traceability.Connections.Where(x1 => x1.Id == this00.r.Id), x2 => x2.Id, x3 => x3.Links.ToArray())

}))

}

The highlighted bit is where the trouble occurs.  I had to make this modification on the server.

I had though that I could abstract the property to a common string using the interface but of course that makes no sense on the server.  I think the answer is to make the common property of the same return type (or base type)
