NHibernate Cascade does not update the associated object yet

Question

Then I use Fluent NHibernate and its autopilot function to display the following simplified POCO classes:

public class Webpage
{    
public virtual int Id { get; set; }    
public virtual string UrlIdentifier { get; set; }    
public virtual WebpageType WebpageType { get; set; }    
}

public class WebpageType
{    
public virtual int Id { get; set; }    
public virtual string Name { get; set; }       
}

Then I redefine the following mapping so as not to explicitly cascade from the webpage to WebpageType:

public class WebpageMap : IAutoMappingOverride<Webpage>
{
    public void Override(AutoMapping<Webpage> mapping)
    {
        mapping.References(w => w.WebpageType).Cascade.None();    
    }
}

For any pure NHibernate readers, here are the xml mappings created fluently:

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true">
  <class xmlns="urn:nhibernate-mapping-2.2" name="EveryPage.Core.Domain.Webpage, EveryPage.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Webpage`">
    <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" unsaved-value="0">
      <column name="Id" />
      <generator class="identity" />
    </id>
    <property name="UrlIdentifier" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="UrlIdentifier" />
    </property>
    <many-to-one cascade="none" class="EveryPage.Core.Domain.WebpageType, EveryPage.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="WebpageType">
      <column name="WebpageType_id" />
    </many-to-one>    
  </class>
</hibernate-mapping>


<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true">
  <class xmlns="urn:nhibernate-mapping-2.2" name="EveryPage.Core.Domain.WebpageType, EveryPage.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`WebpageType`">
    <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" unsaved-value="0">
      <column name="Id" />
      <generator class="identity" />
    </id>
    <property name="Name" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="Name" />
    </property>
  </class>
</hibernate-mapping>

The problem arises when I test that updates are not cascaded in WebpageType via a web page, basically they do !!

I have the following test:

    [Test]
    public void Assert_SaveOrUpdate_On_Webpage_Does_Not_Cascade_Update_To_WebpageType()
    {
        // Get the existing webpage.
        webpage = _webpageRepository.Get("~/testwebpage1.aspx");

        // Update the WebpageType.
        const string webpageTypeName = "qwerty test";
        webpage.WebpageType.Name = webpageTypeName;

        // Save the changes.
        Assert.DoesNotThrow(() => _webpageRepository.SaveOrUpdate(webpage));

        // We need to flush the changes to the store for it to execute the changes.
        Assert.DoesNotThrow(() => NHibernateSession.Current.Flush());

        // Remove the webpage and tag from the level 1 cache so we force a trip to the store on our next check.
        NHibernateSession.Current.Evict(webpage);

        //  Check that the webpageType has not been updated.
        webpageType = _webpageTypeRepository.Get(webpageType.Id);
        Assert.AreNotEqual(webpageTypeName, webpageType.Name);
    }

The above test is wrapped in a global transaction.

The test fails and NHibernate updates the name of the associated WebpageType. Cascades of deleting and saving (creating new ones) work correctly and do not cascade.

I missed the skipped cascade and / or there is a problem with my logic / test.
