The doc says we need to implement the Interceptor.isUnsaved method in order to be able to use the saveorupdate with a persistent object having composite id as primary key. Is there any sample implementation or could someone post the sample for this?

You can also use the unsaved-value strategy on a <version> or <timestamp> property.

is there an explanation on either of these implementations?

Yes, in the documentation.

Hello Christian,
Is there this features without change legacy table (add version)
I send post version and legacy database (in beginners forum) for possible solution ?

regards

Yes, you can use <class ... optimistic-lock="all">, but this only works if you are using a single Session during the long transaction. This is a bit more complex, usually, I really recommend Hibernate in Action for this.

I have Hibernate in Action - is optimistic-lock="all" use all columns in update comand ?

regards

Exactly, in chapter 5.

Ok,
I did exactly what's documented for implementing the Interceptor.isUnsaved method for my entity with composite id key.

http://www.hibernate.org/hib_docs/refer ... ild-update

I just call saveOrupdate for that entity and it seems still its trying to do an insert for already existing records.

Any pointers?

Check if the interceptor is actually called.

Yes, it gets called but the call is always made for onsave of the interceptor.

Are you using 2.1.4 ?

O Initializing Hibernate
Environment I net.sf.hibernate.cfg.Environment Hibernate 2.0.3

That's my console output when hibernate is initialized.
