Hi Adrian,
Your code is right, but an extra setup is needed - DataContext needs
to be decorated in two callback interceptors. I haven't documented it
yet, as we still need to come up with a more transparent procedure.
But here is how I am doing it in my apps:
DataDomain dataDomain = configuration.getDomain("sobf");
// build interceptor sitting between DD and DC - one interceptor can
be shared by multiple DataContexts.
DataChannel postInterceptor = new DataChannelCallbackInterceptor();
postInterceptor.setChannel(domain);
// do this for every ObjectContext used by the application:
// build DC
ObjectStore objectStore = new ObjectStore
(dataDomain.getSharedSnapshotCache());
DataContext dataContext = new DataContext(postInterceptor, objectStore);
// build interceptor ObjectContext used by the application
ObjectContextCallbackInterceptor preInterceptor = new
ObjectContextCallbackInterceptor();
preInterceptor.setContext(new DataContext(postInterceptor,
objectStore));
ObjectContext appContext = preInterceptor;
Note that "appContext" is what your application should be using.

Hello list
I am in the process to migrate my project to Cayenne 3 and doing so I
would like to use the Lifecycle Callbacks. My problem with them is,
that
I can't make them to work.
I am using cayenne-generic-3.0-incubating-SNAPSHOT from 14. 10. 2006.
In the sourcecode I am doing this:
Configuration.initializeSharedConfiguration();
configuration = Configuration.getSharedConfiguration();
dataDomain = configuration.getDomain("sobf");
EntityResolver er = dataDomain.getEntityResolver();
LifecycleEventCallbackMap cbPrePersist =
er.getCallbacks(LifecycleEventCallback.PRE_PERSIST );
cbPrePersist.addListener( CDBCommon.class, "prePersist" );
cbPrePersist.addListener( CThreatAgent.class, "prePersist" );
I have the same sourcecode (last 3 lines) for all of the 7 callback
events.
But neither the CThreatAgent nor the CDBCommon class get's called.
Neither
when I am creating a new DBObject, nor when I am commiting my
changes to
the DataContext.
What am I missing or doing wrong?
Thanks,
Adrian
