Detaching or serializing persistent-nontransactional-dirty instances

[Craig L Russell <Cr...@Sun.COM>]

I need some help resolving what the behavior should be for detaching  
or serializing persistent-nontransactional-dirty instances. This  
behavior was unspecified in JDO 2.0 when we introduced persistent- 
nontransactional-dirty instances.

One point of view is that we should be consistent with serialization  
behavior within a transaction, in which we assume that the  
transaction will commit, and therefore return a detached-clean instance.

The other point of view is that we should not assume that there will  
be a transaction to be committed, and therefore return a detached- 
dirty instance, containing all the changes from the dirty instance.

I'm not sure that I understand well enough the scenarios that would  
argue one side or the other. If there's no consensus we will leave  
this unspecified for now.

Any ideas?
