RavenDB Query: Have to use Customize() instead of Include() - ravendb

Question

I'm getting an error that I'm exceeding the number of requests allowed per session (30) when using this query (using Include instead of Customize):
ApplicationServer appServer = QuerySingleResultAndSetEtag(session => session
.Include<ApplicationServer>(x => x.CustomVariableGroupIds)
.Include<ApplicationServer>(x => x.ApplicationIdsForAllAppWithGroups)
.Include<ApplicationServer>(x => x.CustomVariableGroupIdsForAllAppWithGroups)
.Include<ApplicationServer>(x => x.CustomVariableGroupIdsForGroupsWithinApps)
.Include<ApplicationServer>(x => x.InstallationEnvironmentId)
.Load <ApplicationServer>(id))
as ApplicationServer;
Note, the error occurs on this line, which is called for each AppWithGroup within an application:
appGroup.Application = QuerySingleResultAndSetEtag(session =>
session.Load<Application>(appGroup.ApplicationId)) as Application;
However, this query (using Customize) doesn't create extra requests:
ApplicationServer appServer = QuerySingleResultAndSetEtag(session =>
session.Query<ApplicationServer>()
.Customize(x => x.Include<ApplicationServer>(y => y.CustomVariableGroupIds))
.Customize(x => x.Include<ApplicationServer>(y => y.ApplicationIdsForAllAppWithGroups))
.Customize(x => x.Include<ApplicationServer>(y => y.CustomVariableGroupIdsForAllAppWithGroups))
.Customize(x => x.Include<ApplicationServer>(y => y.CustomVariableGroupIdsForGroupsWithinApps))
.Customize(x => x.Include<ApplicationServer>(y => y.InstallationEnvironmentId))
.Where(server => server.Id == id).FirstOrDefault())
as ApplicationServer;
However, the above query causes an error:
Attempt to query by id only is blocked, you should use call
session.Load("applications/2017"); instead of
session.Query().Where(x=>x.Id == "applications/2017");
You can turn this error off by specifying
documentStore.Conventions.AllowQueriesOnId = true;, but that is not
recommend and provided for backward compatibility reasons only.
I had to set AllowQueriesOnId = true because it was the only way I could get this to work.
What am I doing wrong in the first query to cause the includes not to work?
By the way, another post had the same issue where he had to use Customize. I'd like to do this correctly though.

I'm not sure why the load isn't doing this for you, What version of raven are you on? I just tested this in Raven 2.5 build 2700 and the include is bringing back the information for me in a single request.
Anyway, with the load not working quite like i would expect, i would switch to a set of lazy queries to get what you want in 2 server round trips. http://ravendb.net/docs/2.5/client-api/querying/lazy-operations.
Another option that might work out better for you, (depending on what you are really doing with all of that data) is a transformer. http://ravendb.net/docs/2.5/client-api/querying/results-transformation/result-transformers?version=2.5
Hope that helps.
