The docs are not completely clear to me regarding the dependency between dynamic-update and optimistic-lock attributes in Hibernate 2.1.1. It says

.

Now, does it mean that if I use dynamic-update="false" then...:

1. ...Hibernate does no optimistic locking at all
2. ...non-default values for optimistic-lock ("all" and "dirty") cannot be used, but the default value "version" is still implied and enforced

I'd really love it if the correct answer would be 2.

version and timestamp do work without dynamic-update.

Cool - thx for the quick reply. It seemed to be the intuitive behavior, but the docs really weren't crystal clear about it.

(Well, maybe you just spoiled me with generally crystal clear docs, so I got high expectations...)
