Unsaved Value
This property is available only for Primary Key properties or for properties with Version=True.
It is a property value which indicates that an instance is newly instantiated (unsaved), distinguishing it from detached instances that were saved or loaded in a previous session.
The allowed values of unsaved value are:
| • | any - always save. |
| • | none - always update. |
| • | null - save when identifier is null. |
| • | valid identifier value - save when identifier is null or equals the user-defined value. |
| • | undefined - if set for version or timestamp, then identifier check is used. |
