The datastore can only count up to 1000 results of a query - for your
model you could use an ancestor query.
You are probably better off keeping a counter in the parent and
updating it every time you add or remove a child. Keep in mind that
all writes to the entire group must be executed s
For example, I want to know a number of children. I guess if I just
call list.size()
it could be expensive. What are other ways?
Thank you,
Andrey

Hy, I want to order a query by 'nom' asc and 'prenom' asc :

For that, I somtimes need to specify different Metadata for RDBMD and

You can't avoid the extra datastore query. Since we use a key-value store,
store additional details inside a UserDetail class. Instead of referencing
the User in a property (this creates a 1:N relationship between Usersa and

I have followed those instructions, and I am able to run those tests
with no problems.
However, I can not set up tests for JDO.

You can get this error if you have jars in your JDK's lib/ext folder. The
dev_appserver generally rejects any classes that are found there, because
that feature doesn't make sense under App Engine. (I.E. you just put your
jars in WEB-INF/lib instead).

What I realized now is that the _ah_SESSION variable is not being

not even on the development server (although it works).

Hi,
I have this code that works just fine on the development server but
when I deploy the application, the session isn't created.
What am I doing wrong?
HttpSession session = req.getSession(true);
session.setAttribute("loggedIn", new String("true"));

Update: The serialization is a bug in RPC. I got a workaround for it
