I was changing my mapping files as a result of database changes and I move to use more Foreign Key references and I am now getting the folllowing when updating one of my objects:
object references an unsaved transient instance - save the transient instance before flushing: com.tascon.tim.hibernate.TimUser
I see that this is a known issue and appears to be fixed in 3.0.5, but not in any previous version [2.1.8 for example]. I was trying to avoid upgrading to 3.0.5 if at all possible.
Is there any patch available for 2.1.8?
[b]Hibernate version:2.1.8
