Thanks for the replies.
@Didier - I have considered this, and I guess I will have to manually
delete each entity if I cant find a more elegant solution, however
going by what the documentation says it should just work. I'd like to
find out why this exception is occurring if possible.
@Nichole -
To add to my last comment I could do:
pm.deletePersistentAll(children)
to delete all Child objects in the Parents children Set, however as
the method deletePersistentAll has a void return type how do you
ensure all Child objects have been deleted before I delete the Parent
entity?

Thanks Remy,
I've just had a little play about with the java.util.UUID class. Seems
pretty straightforward. I'll have a look into it a bit more later on, but
maybe it will be overkill for my app - it's only a company internal one so
maybe passing so many characters around might slow my app a
Found it. It seems I have been blind during debugging. I changed an object
without creating a new instance and stored it in an ArrayList. Not really
surprising that both markers had the same position ;-)
The second error still exists. What I found out so far is that it only
occurs in code
Search in google : FishBone GWT objectify ,
A good exemple to use this.

I'm working on an interactive game. I was hoping for turns to be on
the order of 20 seconds or less. It appears the cron framework can
only schedule things in 1-minute intervals. Is there any method for
shorter timers in GAE?

Hi,
i'm interested in using backends for long running processes but i did not
find any real-world example of using backends.
Configuration works fine, backends-api for examination of the
backends-instances seems to be obvious.

Hi Experts,
using GWT 2.3.0 I want to have an additional attribute in every google maps

Ok, I found the reason for the JavaScript error, but have no idea how to
solve this:
The reason is simple. In my scenario MapWiget itself also has a click

from the map everything works fine. As I said above I would
Would queued tasks in general, and deferred tasks in particular, suit

You could use a scheduled task for a heartbeat of interval 1 minute,

I just let the datastore do it. I like having Long ids:
* Longs always stick out in code as an id - ie in a constructor with
15 things, it sucks when they are all Strings. I often wish Java
supported C-style typedefs (or just allowed subclassing basic types).
* Long keys are more

Just a quick addition: you actually have something in between an
owned and unowned one-to-many
because you're holding on to object references to your many.
The unowned one-to-many would use SetKey childrenKeys, for example.
