Looks like you're trying to store something like:
class Announce {
Long id;
User user;
}
class User {
Key id;
Type type;
}
So you store User first and then try to create a new Announce with
that stored user set in Announce.user.
You can't do that. You can't change the parent of an entity once it's
stored. You have Announce->User as an owned relationship. If you
want to store the User first and then reference it from Announce,
you'll need that class to look more like:
class Announce {
Long id;
Key userId;
}
The Google documentation covers relationships.
