Question

I am using SysCache2 and NHibernate 2.1.2.4.

No matter how hard I try, NHibernate keeps loading previous instances of an entity.

My class is mapped as cacheable ReadWrite.

The cache region is the default, i.e. the full name of the class’s types.

I am performing all actions within a transaction.

The database is definitely being updated, and when I manually clear ASP .NET’s cache, the problem goes away.

I am doing a simple update, like this:

using(var transaction = NHSession.BeginTransaction())
{
    var foo = Session.Load<Foo>(_fooId);

    foo.Name = "A new name";

    transaction.Commit();
}

Then I reload the entity later on (in a different session within the application), like this:

using(var transaction = NHSession.BeginTransaction())
{
    var foo = Session.Load<Foo>(_fooId);

    Response.Write(foo.Name);

    transaction.Commit();
}

… but Foo’s name is still the old name, not the new name I just updated it to!

I worked this one out – for certain reasons I had two Session Factories. I didn’t realise that the Save operation was occurring within one factory, and the load was occurring in the other.
