RavenDB does not set all the properties on store

I have a really weird scenario where I try to store domain events (I'm trying to learn CQRS and RavenDB at the same time). The basic structure of the documents I try to store are:

public interface IDomainEvent { ... }    
public abstract class BaseDomainEvent : IDomainEvent { ... }
public class DomainEventA : BaseDomainEvent { ... }
public class DomainEventB : BaseDomainEvent { ... }

Given that I want to store DomainEventA and DomainEventB in the same collection in RavenDB and I have managed to do so. But the problem is that in the collection I am missing the properties of DomainEventB, and not all properties are set even though I have checked that the properties are set before I commit the transaction where I store the objects. The following gist shows a working example of what I want to do: https://gist.github.com/2830093, and the test code that fails me is found in this test: https://github.com/mastoj/TJ.CQRS/blob/ravenfail/TJ.CQRS.RavenEvent.Tests/RavenEventStoreTests.cs that is using this RavenDB code: https://github.com/mastoj/TJ.CQRS/blob/ravenfail/TJ.CQRS.RavenEvent/RavenEventStore.cs.

I really can't get my head around this one.

EDIT 1: I can add that in the failing scenario the metadata of the stored object says it is one type but the properties for that type is not stored.

I planned to delete or vote for close but I think more than me might experience this problem at some point. I found the solution in my case and it was that the objects I added to RavenDB had a faulty equals method so RavenDB thought that all my objects were the same one. When I added one more property to check in the equals method everything start working as expected.
