This problem lasts for 3 weeks on Google AppEngine console.
I switched to another applicationId, and everything was good for few
moments - i was able to see my data.
But now again - Server error and no way to see my data via admin
console.

You'll need to add an index property to your entity and specify this
index in your query.

ok, let's say i want to retrieve entity from result list starting from index
1100 to 1150.
how to achieve this ?
1000 is a hard limitation on every query. So if you have 5000
entitties and use range 999-1500 you will get only one record. The
only way is to iterate through entities using JDO extend.

But if the purpose of your relationship is only to manage child class

Hi, Chris,
Scala is quite interoperable with Java. Wouldn't it make sense to
write data objects in Java and use them from Scala? Or maybe wrap them
into Scala classes to take advantage of Scala facilities? It is, of
course, more work, but it will keep your design clean and should avoid
