Nibernate incomprehensible behavior

I am working on an old application using nhibernate 4.4.0400 to connect to oracle DB.
The save update command look like this:
CallContext.Session.Save(obj); // Save or update the data record on database
transaction.Commit();
obj.MutCounter++;
Transaction created as follows:
using (ITransaction transaction = CallContext.Session.BeginTransaction())
{...
Edit:
Method call is defined as this:
public static void SaveOrUpdate(T obj)
{
if (obj == null)
throw new ArgumentNullException("obj");
Session is defined as follows:
public static ISession Session
{
get
{
if (HttpContext.Current == null)
throw new MissingHttpContextException();
if (HttpContext.Current.Items[HttpContextItemEnum.Session] == null)
HttpContext.Current.Items[HttpContextItemEnum.Session] = NHibernateHelper.OpenSession();
return HttpContext.Current.Items[HttpContextItemEnum.Session] as ISession;
}
set
{
if (HttpContext.Current == null)
throw new MissingHttpContextException();
HttpContext.Current.Items[HttpContextItemEnum.Session] = value;
}
}
On first call (click first time save button in the UI), I get the following exception:
Unique Constraint (...) verletzt
Could not synchronize database state with session
But if I click a second time right after (some seconds), the data are saved properly in the DB.
I don't know what is wrong, why I get this behavior, what I have to change to get a stabile behavior
Do you have any idea what to check? What to change? Why is this happening like this?

Why you are callingCallContext.Session.Save(obj);? Can you post a code few lines above it? How theobjis constructed?

Hi Amit, the obj is given by the caller: See my Edit in the question. We ensure that the object exists. The object is an entity (Business object) and I checked that all mandatory data are set adequately.

The CallContext.Session.Save refers to the NhibernateHelper which will do the saving.
