2) Initial quick and simple solution based on JAX-RS and JPA:
- We have versioning in JPA (optimistic locking) - Use it (send 409 on server and send
right data)
-- Use JAX-RS ExceptionMapper for exceptions around the optimistic locking ?
Added handling of OptimisticLockException to forge https://github.com/forge/core/pull/481
this will give clients a 409 so that they could show to the user that their copy was out
of date. Now the client still need to react to this.
- Client library will have helper methods for managing data
POC of client handeling this
https://github.com/edewit/aerogear-push-quickstarts/tree/conflict/client/...
this will just show the client version and the server version and the user can choose
which version to take
- Use push to send notifications that data changed?
- JAX-RS Annotation to send notifications?
