> Priority: Major

> 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?
