I need a hint. I'm running JUnit tests on a local datastore. I have
multiple tests that pass when run by themselves and fail when run with
the other tests. The specific failure is a DataStoreFailureException
with detail message: ApplicationError: 3: handle 14 not found.
The stacktrace is

That would be a cool feature though!
But deploying an app will not modify your local datastore. However, I
have occasionally had my local datastore just reset itself without
warning. Basically the local sdk is for

quickly sometimes.
Thanks John and Jeff for sharing the knowledge.
I've just quickly scanned your project home, and I have a novice question
that needs your help:

use your framework alone, or should use in combination with JDO / JPA

Hi Chau, yes both Objectify and Twig replace JDO/JPA. I think that
