I have the answer. With help from the folks at Google I was told that
the underlying problem was a ClassNotFoundException for isSerializable
from the GWT toolkit.
This explains why my other app worked ok, because it contained the GWT

This also means that the true problem was being masked by
Yes, it's the same bug.
But the proposed workaround seems to be irrelevant.
And, the bug is coted 'Priority-Medium'
I think that such a bug on the caching mechanism in a web
infrastructure is a major bug: be unable to manage the expiration
delay of cached objects is a critical problem

You want to manipulate Telephone separately, independent of its-owner-to-be,

Similarly, you will have another class for Person.

Hi Jake,
If we (as the Google Plugin for Eclipse team) do an FAQ on Maven + App
Engine, it would be simply describe how to get such a setup working with
Eclipse. I must admit that I have not worked through all the details yet,
but in theory if you have an App Engine project working with Maven,
I'm doing this too. Turn that task into one that takes parameters - a
start and end index. You set a threshold of the biggest number of
tasks that can be kicked off in one execution. Let's say it's 50.
So, you're given 1 to 5000... So, you kick off a task that spawns off
new instances of itself

We removed this from the documentation because it was not working, and
the fix turned out to be much more involved than we had originally
anticipated, so the fix isn't coming out in 1.3.2. I can't comment on

Hi!
We've developed two means of interacting with the datastore
seperately- one is a flex GUI which uses GraniteDS remoting to persist

translates datastore information to XML and allows it to be retrieved
using HTTP requests.
Hi:
Congratulation and thank for tremendous efforts from the Objectify Team.
By the way, has any one attempted Objectify with possible very large

When GAE is load balancing your app, and it decides to start up a new
instance, why are they sending a client request as the first hit to
your app? Unless your app is trivial, you're going to have some
startup time. It's not a good job of load balancing if requests are
sent to an instance that
