    <p>I've the following class:</p> <pre><code>public class Customer { public virtual int CustomerID { get; protected set; } public virtual string AccountNumber { get; protected set; } public virtual string CustomerType { get; set; } public virtual int TerritoryID { get; set; } public virtual SalesTerritory Territory { get; protected set; } } </code></pre> <p>And it is being mapped using Fluent NHibernate as follows:</p> <pre><code> public class CustomerMapper : ClassMap&lt;Customer&gt; { private const string schema = "Sales"; public CustomerMapper() { SchemaIs(schema); Id(x =&gt; x.CustomerID); Map(x =&gt; x.CustomerType).WithLengthOf(1).Not.Nullable(); Map(x =&gt; x.TerritoryID).Not.Nullable(); Map(x =&gt; x.AccountNumber).ReadOnly() .Update(false) .Insert(false) .Generated(Generated.Insert); References&lt;SalesTerritory&gt;(x =&gt; x.Territory).TheColumnNameIs(ReflectionHelper.GetProperty&lt;Customer&gt;(x =&gt; x.TerritoryID).Name).LazyLoad().Update(false).Insert(false); } } </code></pre> <p>The Update and Insert methods are just extension methods that set the <strong><em>update</em></strong> and <strong><em>insert</em></strong> attributes of a property in the generated mapping file.</p> <p>This is how the resulting mapping file looks:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-lazy="true" assembly="Model" namespace="Model" schema="Sales"&gt; &lt;class name="Customer" table="`Customer`" xmlns="urn:nhibernate-mapping-2.2"&gt; &lt;id name="CustomerID" column="CustomerID" type="Int32"&gt; &lt;generator class="identity" /&gt; &lt;/id&gt; &lt;property name="AccountNumber" column="AccountNumber" insert="false" update="false" generated="insert" length="100" type="String"&gt; &lt;column name="AccountNumber" /&gt; &lt;/property&gt; &lt;property name="TerritoryID" column="TerritoryID" not-null="true" type="Int32"&gt; &lt;column name="TerritoryID" /&gt; &lt;/property&gt; &lt;property name="CustomerType" column="CustomerType" not-null="true" length="1" type="String"&gt; &lt;column name="CustomerType" /&gt; &lt;/property&gt; &lt;many-to-one lazy="proxy" update="false" insert="false" name="Territory" column="TerritoryID" /&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre> <p>My problem is that when a save a new customer instance into the database, the customer instance have its Territory property as null.<br/> How can I make this property to contain the correct value after saving into the database? I am looking at something like the <strong><em>generated</em></strong> attribute for properties which retrieve the correct value after the session is flushed.<br/> Or is there something wrong with my Customer class? <br/> Thanks in advance.</p> <p><strong>EDIT 1:</strong> The database that I'm using for this model is AdventureWorks (SQL2005), tables Sales.Customer and Sales.SalesTerritory.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
