Hi,

If I save details to the datastore with something like....


User user = userService.getCurrentUser();
Entity greeting = new Entity("Greeting", guestbookKey);
greeting.setProperty("user", user);


That user then changers their nickname,

I then query the datastore for that greeting entity.

I then display properties from the user object I saved will those details 
be up to date? so will it now show the users new nickname?


If not can I save the userID and then is their an api to get user details 
based on an ID?

Thanks
Aidan
