Hi,

I got a web solution (aspx) that uses nHibernate.

Im using the same nHibernate session for all users that means i only create one session and then reuse it.

My problem is when i have the same object open in two different tabs in ex. Crome when i update the object on one of the pages i get the
"a different object with the same identifier value was already associated with the session"

My update function looks like this now:
public virtual void Update(object entity)
{
ValidateSession();
if (entity == null)
return;

var ownTrans = !Session.Transaction.IsActive;
if (!Session.Transaction.IsActive)
Session.Transaction.Begin();
try
{
Session.SaveOrUpdate(entity);
if (ownTrans)
{
Session.Transaction.Commit();
}
}
catch (Exception exp)
{
if (ownTrans)
Session.Transaction.Rollback();
throw (exp);
}
}

Any ideas to what i have done wrong?

Jacob

I believe that you will have to evict the object from the session it was loaded in before that session is closed.
