Answer 1

I tried @claitonlovatojr's hack, but I couldn't still handle the error.

All I had to do in my case wasy to replace my ISession.Update(obj) call to ISession.Merge(obj).

In your repository, change:

public void Update(Company company)
{
    using (ITransaction transaction = _session.BeginTransaction())
    {
        //_session.Update(company);
        _session.Merge(company); // <-- this
        transaction.Commit();
    }
}
