InstanceLifecycleListener on detached instances
Hi,
Instance lifecycle listeners are only invoked if a PM is involved, but for
detached instances none are called. The dirty listener is one that IMO could be
called for detached instances. It means during detachment, a Dirty listener is
assigned from the attached to the detached instance.
Any thoughts?

Hi Erik,
Ah. I missed the context earlier. I don't see any technical issues.
My biggest concern is that it's getting late in the cycle to add new
features.
What do other experts think? Is it worthwhile to open the spec for this?

Craig,
A callback called when a detached instance is changed. (gets dirty)

Hi Erik,
JDO 2 did not define any additional instance lifecycle callbacks, so
there are none for JDO 2 features.
The dirty callback is executed during a lifecycle change from clean
to dirty, so it's not really suitable.
What problem are you trying to solve?
