The principal reason for these JDO lifecycle callbacks is so that Isis can
keep its internal caches (IdentityMap) of domain objects in sync with Isis.
But now that Isis uses JDO as its ORM, I'm pretty certain that they
provide no actual benefit.
So in a future version (probably not 1.8.0, but most likely 1.9.0) I'm
considering getting rid of these internal maps. If 1.7.0 doesn't fix
things for you, we can consider bringing forward that work to tidy up this
part of Isis.
That's not to say that the callbacks will go completely... in your
particular case we will still need a callback in order to support auditing
("enlistDeleting"). But simplifying the codebase will help make it easier
to rationalize as to what the correct behaviour should be.
Cheers
