The automatic update of the data itself
will be available in the Framework, the data services is what allows for
automatic transfer back to the server.
The cell renderer APIs may help show you
what can be done in Flex 2 as well.
Matt
This will be handled in the
Flex2 data services. More importantly is
that the changes (inserted, added and deleted
buffers) will be
marshalled to the server as needed and can be
bound to a persistence
adapter (say Hibernate) to even manage updating
the data store with
the changes.
That's where the real power comes in.
