How to refresh a collection?

Hi,

how to refresh a collection of an entity? I have an entity which has many collections. and I don't want to refresh the whole entity (to avoid unnecessary DB traffic) but only one collection. The Session.refresh() method only accepts an entity and not a collection.

Is there a solution?

Regards, Markus

Don't know what's your usecase but you can evict your object and reload it with an hql query that only join fetch the collection you want

Thanks for your reply but I do not want to evict the root object because I need the data. I can refresh the whole root object, but this refreshes all associated data.

I want to refresh only one collection to avoid unnecessary db access...
