Are all method calling the makePersistent method needed to be

Is this a bug..??
No one has any consideration???

Hi Vik,
You can try using a source control control. Some source control tools
allow you to deploy a specific file instead of the whole solution. In
your case, if you only want to deploy 3 modified files, you can just
select these 3 files and deploy it.

When there is no data persisted by my appilcation, the only thing that
makes my datastore grow is _ah_SESSION Entities
(session data backed up by the database).
Maybe it's the same thing in your case?

Yes, please provide more information if you can. There was a bug fix in
1.2.5 that made queries respect fetch groups, but JPA doesn't have fetch
groups so the error you're reporting suggests that something is wrong here.
Can you boil it down to a small snippet that reproduces the problem?

You can't filter by the name component of the key because the datastore
doesn't support this. You can only filter by the entire key. Why can't you
create the key by hand? KeyFactory.Builder should have everything you need
to do this.

You shouldn't need the @Persistent(valueStrategy =

App Engine applications cannot share datastores. That means that you will
not be able to connect directly to another application's datastore for
querying, etc. To replicate this in App Engine, you'll have to set up a web

Engine's

JPA doesn't have "fetch groups" as such, just a "default fetch group".

Hi Ken. This is a known issue -- one-to-many owned relationships of the same

unowned relationships (list of keys) instead which should work.

Hi Jason,
Thanks for the response. I'm seeing it in the development environment.
I can't even get ahold of a stack trace in production because the
logged events I try to throw just aren't reaching the Logs manager. I

Hi Erum. App Engine doesn't support this callback, so when sessionDestroyed
is triggered by the development server, it's not within an active request
and hence the exception that you're seeing. In the production environment,
you would see a similar result if the callback is even triggered at all.
