How to map timestamped or versioned data inside a component.

Hello. I have some questions regarding versioned and timestamped data. I understand that Hibernate provide the way to specify if a field contains versioned or timestamped data via <timestamp> and <version> tag. But can I map those fields inside a component. Does Hibernate support those tags inside <component> tag like

Code:

<component ......>
   <property ...../>
   <property ...../>
   <property ...../>
   <timestamp ..../>
</component>

Best regards.

No, only directly inside the <class> element. However, if you database is doing the versioning for you, you can map the columns in a component using <property formula="YourColumnName">.

If you need to have hibernate do the versioning, you'll have to map the class explicitly.
