Hi,

I am very new to ZK, and am working on integrating an existing Spring+Hibernate framework with the ZK UI. I have read the Small Talk and HOWTO related to integrating Hibernate + ZK (+Spring), but haven't yet been able to answer this question for myself.

The problem I am encountering is that in our application the Hibernate Session that is being bound to the thread by an OpenSessionInViewFilter object is not available to all of the ZK processes that serve that request. (At least, this is my analysis so far.) I'm assuming that this is because ZK handles events in separate threads, so the onCreate() event for a ZK component might be part of the same request, but won't have access to that Filter-bound Hibernate Session.

What I'm wondering is where is the correct/best place to store these "per-request"
objects like the Hibernate Session. All threads that handle a single request need access to that object, but clearly it cannot be shared with threads that are handling other requests. Is this something that the Execution interface was designed to address?

Thanks in advance -
Hans
