Well as i found out, session attributes don't always guarantee that
they are sent back to the same JVM thus i keep getting null objects in
my view. While i saw a similar discussion before the only examples i

Is there a way to query for entities based on their grandparent?
For example, suppose we have a root A entity, a B entity having A as
parent, and a C entity having B as parent (A - B - C). Is is
possible to query for all C entities in the database that have A
entity as grand parent?
Thanks
I'm not sure about adding a TemporaryTaskFailure
(TransientTaskFailure?) exception, but regardless of whether we do or
not, it seems that the Deferrable.doTask method should be declared to
throw Exception. Otherwise, implementations will be restricted to
throwing only RuntimeException (or

Really ? You mean an org.datanucleus.sco.backed.ArrayList that

It's critical that the GAE team take these concerns on board. The two
selling points of GAE are performance and reliability, yet thanks to
the aggressive unloading of idle instances and the constant glitches
of the GAE infrastructure, GAE is dramatically underperforming against
expectations
Ilya,
Are you looking to persist objects for a lifetime of a session, or are you
looking to minimize the logic you are using in your JSPs?
As a general design principle, we recommend that you minimize usage of
session scope. Variables bound to session scope are serialized and stored to

It really depends on what you're doing. One of the challenges of developing
on a distributed store like the App Engine data store is adjusting the way
you approach persistence for objects. For instance, suppose you store
favorite colors per application user. The canonical way of solving this

Yeah, I was afraid of the relations part. In the use case I'm
dealing with, there are no relations, but maybe the JDO layer can't
infer that. For now I won't worry about it. If it turns out the
