DataDomain instantiates with null EventManager
----------------------------------------------

                 Key: CAY-871
                 URL: https://issues.apache.org/cayenne/browse/CAY-871
             Project: Cayenne
          Issue Type: Bug
          Components: Cayenne Core Library
    Affects Versions: 2.0 [STABLE]
         Environment: MacOSX 10.4, Java5, Cayenne 2.0.2
            Reporter: Emilian Bold
            Assignee: Andrus Adamchik


DataDomain instantiates with an empty event manager which later leads to a NPE in DataRowStore.sendUpdateNotification.

This makes the bug look as if it's a serialization issue (see https://issues.apache.org/cayenne/browse/CAY-796) but actually all DataDomain expects is something like:

dataDomain.setEventManager(EventManager.getDefaultManager());

This seems quite confusing for an API client as, unless you actually listen for events, you don't care about the EventManager and expect it to be set beforehand.

Initializing DataDomain with the default manager which may be replaced at will via setEventManager seems like a better approach.
