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.
