    <p>I've either misunderstood the NHibernate manual or I've done something wrong. Can anyone help?</p> <p>I am trying to retrieve a User without the AuditLogEntrys. But NHibernate is still loading the AuditLogEntrys. I only want the AuditLogEntrys loaded when I access the property.</p> <pre><code>public class User { public virtual int UserId { get; set; } public virtual string UserName { get; set; } public virtual IList&lt;AuditLogEntry&gt; AuditLogEntrys { get; set; } } public class AuditLogEntry { public virtual int Id { get; set; } public virtual DateTime DateRead { get; set; } public virtual string MachineName { get; set; } } </code></pre> <p>Mappings:</p> <pre><code> &lt;class name="Model.User, Model" table="User" lazy="true"&gt; &lt;id name="UserId" access="property" column="UserID"&gt; &lt;generator class="native"&gt;&lt;/generator&gt; &lt;/id&gt; &lt;property name="UserName" access="property" /&gt; &lt;bag name="AuditLogEntrys" lazy="true" access="property"&gt; &lt;key column="UserID" /&gt; &lt;one-to-many class="Model.AuditLogEntry, Model"&gt;&lt;/one-to-many&gt; &lt;/bag&gt; </code></pre> <p></p> <pre><code> &lt;class name="Model.AuditLogEntry, Model" table="AuditLog" lazy="true"&gt; &lt;id name="Id" access="property" column="ID"&gt; &lt;generator class="native"&gt;&lt;/generator&gt; &lt;/id&gt; &lt;property name="DateRead" access="property" column="DateRead"&gt;&lt;/property&gt; &lt;property name="MachineName" access="property" column="MachineName"&gt;&lt;/property&gt; &lt;/class&gt; </code></pre> <p>Code to get the user:</p> <pre><code> public IList&lt;User&gt; GetUserByUserName(string userName) { ICriteria criteria = NHibernateSession.CreateCriteria(typeof(User)) .Add(Expression.Eq("UserName", userName)); return GetByCriteria(criteria); } </code></pre> <p>Now I'd expected a User object with an empty collection of AuditLogEntry's, but this is not what is happening.</p> <p>Any ideas?? Thanks.</p>

    1. COHow are you checking your AuditLogEntrys collection? Are you inspecting it in the debugger or are you watching via SQL Profiler?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
