Hello
I've been using hibernate for a while now with my application.
Lately i started optimizing the code and applied the structure
from well known "Hibernate in Action".
Now I have a thread-local session.
It works very nice but I started getting "a different object with the same identifier value was already associated with the session" exceptions.

I think I know the reason.
First I load "model" list to show it on the screen for selection by users.
When the user selects particular model I'm trying to load it again with all the details for it.

Question:
What is common way of doing it?
Should I load the whole list of "models" and keep it in the session and work only on this list without reloading it again from the DB ?
The way I wanted to do it is
1. Load the list just do display "model" names for selection.
2. When selected load that model from the DB

Problem is that that list of models is stuck somewhere in hibernate objects and I currently don't have access to it.

Or may be I should evict each "model" from the list after loading ?
