Using aliases in anonymous types causes LINQ query to return NULL values

[Vlad Novgorodov]

Hi,

I'm using RavenDB 472. When my LINQ query uses aliases in the
anonymous type ("Name", "Address" in the example below) the query
returns correct number of records but the aliased fields are empty. If
I don't use aliases everything works fine.

var documentStore = new DocumentStore() { Url =
"http://localhost:8080" };
documentStore.Initialize();

using (var session =
documentStore.OpenSession("TestDB"))
{
var results =
session.Query<CompanyView>().Select(x => new
{
Name = x.CompanyName,
Address = x.CompanyAddress
}).ToArray();
}

Thanks, I've added a failing test and we will have a look at that soon

I've just checked build 573 - yes, it's fixed. But the same problem
rises if I use predefined type instead of anonymous one:

Select(x => new MyType

Can you show a full failing test?

public class SampleDocument
{
public Guid DocId;
public string Name;
}

public class ProjectedDocument
{
public Guid MyDocId;
public string MyName;
}

public void Test()
{
Guid docId = Guid.NewGuid();
_session.Store(new SampleDocument { DocId = docId, Name =
"Doc1" });
_session.SaveChanges();

var result = _session.Query<SampleDocument>()
.Select(x => new ProjectedDocument
{
MyDocId = x.DocId,
MyName = x.Name
})
.First();

System.Diagnostics.Debug.Assert(result.MyDocId !=
Guid.Empty);
System.Diagnostics.Debug.Assert(!
string.IsNullOrEmpty(result.MyName));
}

Thanks, this will be fixed in the next build
