-------------------------------------
I don't understand the problem. You can use anything for the key. Struts can't
know anything about hibernate.
> s:select tag to support key as tupple (Number, Number)

> Key: WW-3310
> URL: https://issues.apache.org/struts/browse/WW-3310
> Project: Struts 2
> Issue Type: Improvement
> Components: Core Actions
> Affects Versions: Future
> Reporter: Zarko Lozanoski
> Priority: Minor
>
> Currently s:select tag has a nice feature that a Long key can be used -
> possibly in combination with a persistence provider like hibernate.
> When optimistic locking strategy is used, this Long key value does not
> uniquely identify the entity to be selected, because that entity can be
> changed by another transaction during the user think time (application
> session). If a version is added to the key, that will solve the optimistic
> locking problem nicely.
