Here is an overview of the issue:
---------------------------------------------------------------------
Key: HB-496
Summary: Version and unsaved-value
Type: New Feature
Status: Unassigned
Priority: Major
Project: Hibernate2
Components:
core
Versions:
2.1 beta 6
Assignee:
Reporter: Emmanuel Bernard
Created: Mon, 24 Nov 2003 11:08 PM
Updated: Mon, 24 Nov 2003 11:08 PM
Environment: Hibernate CVS head of branchv21 nov 25
Description:
Here is a patch allowing unsaved value for version. This is useful for saveOrUpdate() assigned id and having version as primitive type.
Version unsaved-value can be:
* undefined: let the saveOrUpdate choice to id's unsaved-value
this is the default to prevent mapping break down primitive type version)
* null: save if version==null, update otherwise
* negative: save if version < 0, update otherwise (allowed for short, int, long only)
Timestamp unsaved-value can be:
* null: I think this is the only needed behavior. I don't know how undefined could be useful.
