Hi all,

I'm just getting started with EMF Transactions. So far I'm finding it very
useful. But, I'm having trouble with creating a NotificationFilter that
does what I want. Here is my scenario:

I am writing an RCP application that uses an EMF model to hold both runtime
and persistent data. The persistent data are managed by Teneo/Hibernate and
are contained by a hibernate://.. Resource inside my
TransactionalEditingDomain. The runtime data are contained by a different
Resource that is also inside my TransactionalEditingDomain.

I would like to have a ResourceSetListener that only responds to NOT_TOUCH
type changes on EObjects contained by the hibernate://.. resource. This
listener should respond to such events by calling save() on the
hibernate://.. resource to keep the database in synch with the live
application data.

I don't know how to construct the proper NotificationFilter to return from
the ResourceSetListener. None of the set of available static filters nor
any of the create...Filter() methods provided by class NotificationFilter
seem to fit my needs, and I'm not allowed to create a custom
NotificationFilter because it's constructor is declared with default
visibility.

What am I missing?

I'm currently using EMF Transaction SDK 1.1.0.v200612220820.

Thanks,
Chris
