Hello,

If I understood right I can create a Key for persisting an new entity,
which shall live in a entity group, like this:

KeyFactory.createKey(parentEntityKey, newEntity.class.getSimpleName(),
1l));

is it possible, that appengine generates the last part (here 1L) of
the key, beause I don“t know, which keys are already in use.

Tnx
Frank
