Cannot read state after grain deactivation

[crodriguezvega]

Hi,

I have included the project Orleans.StorageProvider.DocumentDB in my solution because I am interesting in using this provider. I had to make a small modification on the code to make it build with the release 1.0.10 of Orleans, because it does not include the interface IGrainState anymore. Thus, I changed the references of IGrainState to GrainState.

I am running a scenario where I explicitly deactivate a grain and I activate it again on the next message. When doing that I get an error on line 60 of DocumentDBStorageProvider.cs, which reads:

grainState.SetAll(document.State);

The exception that is thrown is:

{"Object of type 'System.Int64' cannot be converted to type 'System.Int32'."}

The state of my grain includes just an integer:

public class ProcessorState : GrainState {
public int Number { get; set; }
}

The exception is thrown after deactivation has completed and I am sending a new message to the grain expecting it to read the state from DocumentDB and activate again.

I am using DocumentDB client 1.3.0, Orleans 1.0.10 and Newtonsoft.Json 6.0.4.

Thanks.
