                 Key: OPENJPA-673
                 URL: https://issues.apache.org/jira/browse/OPENJPA-673
             Project: OpenJPA
          Issue Type: Bug
            Reporter: Pinaki Poddar
             Fix For: 1.2.0


Entities using GeneratedValue for primary key, a version field an dno detached 
state fails to merge.

The issue lies with identifying :"what makes a new instance?"

It is not obvious why VersionAttachStrategy does not use version field to 
detect newness. Instead it depends on detached state which is obviously null 
for instances not using a Detached State.

Can someone shade some light on why VersionAttachStrategy ignores version field 
to detect newness?
