Yeah, I am leaning towards merging the callback code into the base
context... The ability to proxy an ObjectContext is very nice, but
it changes a few standard Cayenne assumptions about the object
context. I guess for such fundamental functionality like callbacks,
we shouldn't be doing that.

CAY-797
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Environment: 3.0-prerelease svn 523667
Reporter: Lachlan Deck
Assignee: Andrus Adamchik
Say you create a callback intercepted context as described here
(http://cayenne.apache.org/doc/lifecycle-callbacks.html), or as in
my case created a subclass of ObjectContextCallbackInterceptor to
wrap these concepts.
ObjectContext myContext = new CallbackInterceptedContext();
Object a = myContext.newObject(SomeClass.class);
Object b = myContext.newObject(SomeClass.class);
myContext.equals( a.getObjectContext() ); // false (unless I
override equals to provide a better test)
a.getObjectContext().equals( myContext ); // false
a.getObjectContext() == myContext; // false
a.getObjectContext().equals( b.getObjectContext() ); // true
So this gets a little messy having to essentially test in the
correct direction. Now, I understand why this occurs (because the
CallbackIntercepting essentially provides a proxy context for the
context it contains) but it seems to me that this leads to some
difficulties like the above that could possibly be more easily
overcome were both DataContext and CayenneContext to implement
callback intercepting directly.
Thoughts?
