Hi, firts of all sorry for my not so good english, i'm using Csla 3.0.5, my Dataportal is WcfProxy, when i reatreave an object with SqlGuid field and that field is Null from the database i get this exception:

The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://ws.lhotka.net/WcfDataPortal:FetchResult. The InnerException message was 'ValueType 'System.Data.SqlTypes.SqlGuid' cannot be null.'. Please see InnerException for more details.

I googled for a coupled of hours and for my surprise i didnt find nothing about this particular issue, can anybody help me on this?

Thanks

WCF Web API and Csla.ApplicationContextUser

I am in the process of creating a RESTful service layer leveraging the WCF Web API and I just need some clarification and/or confirmation that the Csla.ApplicationContextUser will not change during the method call.

An example of one of my methods looks like:

       [WebInvoke(UriTemplate = "workspace?token={token}", Method = "PUT")]
        public HttpResponseMessage<WorkspaceEditData> UpdateWorkspace(string token, WorkspaceEditData data)
        {
            AuthenticationHelper.ValidateToken(token);

AuthenticationHelper.Login(token);

var workspaceEdit = WorkspaceEdit.FetchWorkspaceEdit(data.WorkspaceId);

workspaceEdit.Description = data.Description;
workspaceEdit.Name = data.Name;

            if (workspaceEdit.IsValid)
            {
                workspaceEdit = workspaceEdit.Save();
            }

var workspaceData = new WorkspaceEditData(workspaceEdit);

AuthenticationHelper.Logout();

return new HttpResponseMessage<WorkspaceEditData>(workspaceData);
}

Will the user that is logged in via my method that does a LoadPrincipal based on the token/username ... be the same throughout the method call?
