Hi,
Things have changed in 1.2 and the outdated 1.1 documentation is
falling behind. A static EventManager is no longer used. Instead an
EventManager is attached to a DataDomain. So you can do something
like this:
DataDomain domain = Configuration.getSharedConfiguration().getDomain();
DataRowStore cache = domain.getSharedSnapshotCache();
domain.getEventManager().addListener(this, "snapshotsChanged",
SnapshotEvent.class, cache.getSnapshotEventSubject());
Andrus
P.S. Thanks to Cris and Kevin, we now have all 1.1 documentation
residing on Wiki, so it should improve significantly in the following
releases.
