    <p>I've got an Order class that contains OrderItems. When I save the Order class, the database is populated with the Order information, but none of the child OrderItems are saved to their respective tables. Here's what the Order mapping looks like:</p> <pre><code>&lt;class name="Order" table="Orders"&gt; &lt;id name="OrderID" column="OrderID" type="Int64" unsaved-value="0"&gt; &lt;generator class="identity"/&gt; &lt;/id&gt; &lt;list name="OrderItems" table="OrderItems" inverse="true" &gt; &lt;key column="OrderID"/&gt; &lt;index column="OrderItemID" /&gt; &lt;one-to-many class="OrderItem" /&gt; &lt;/list&gt; </code></pre> <p></p> <p>Here's what the OrderItem mapping looks like:</p> <pre><code>&lt;class name="OrderItem" table="OrderItems"&gt; &lt;id name="OrderItemID" column="OrderItemID" type="Int64" unsaved-value="0"&gt; &lt;generator class="identity"/&gt; &lt;/id&gt; &lt;property name="OrderID" /&gt; &lt;many-to-one name="Order" class="Order" column="OrderID" not-null="true" /&gt; &lt;/class&gt; </code></pre> <p>Here's what the code to save the Order looks like:</p> <pre><code>if (o.CreatedBy == null || o.CreatedBy == string.Empty) { o.CreatedBy = userID.ToString(); foreach (OrderItem oi in obj.OrderItems) { oi.CreatedBy = userID.ToString(); oi.ModifiedBy = userID.ToString(); oi.ModifiedOn = DateTime.Now; } } o.ModifiedBy = userID.ToString(); o.ModifiedOn = DateTime.Now; ISession session = NHibernateHelper.GetCurrentSession(); ITransaction tx = session.BeginTransaction(); session.Save(o); tx.Commit(); NHibernateHelper.CloseSession(); </code></pre> <p>Any idea why the child OrderItems aren't being saved?</p>

    1. COCould you post a bit of your code to show how your objects are created, relationships established, and then saved? Your mapping looks fine so my guess is that it's code related.

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.
