    copied!<p>I have three classes that pose a problem when trying to add a new child.</p> <p>They are:</p> <pre><code> User { List attributesGroup&gt; } AttributesGroup { attributesGroupId value } AttributesGroupId { attrName userId } </code></pre> <p>The mapping is: </p> <pre><code>&lt;class name="AlternativeUserAttributes" table="`AlternativeUserAttributes`" lazy="true"&gt; &lt;composite-id name="Id" class="Data.Entities.AlternativeUserAttributesId"&gt; &lt;key-property name="AttributeName" column="`attributeName`" type="string" /&gt; &lt;key-many-to-one name="User" class="Entities.User" column="`userId`" /&gt; &lt;/composite-id&gt; &lt;property name="AttributeValue" column="`attributeValue`" type="string" /&gt; &lt;many-to-one name="User" column="`userId`" cascade="none" not-null="true" /&gt; &lt;/class&gt; </code></pre> <p>I can remove items and class SaveUpdate on the user class without issue, however when I try to add an item to the collection via:</p> <pre><code> AlternativeUserAttributes aua = new AlternativeUserAttributes(); aua.Id = new AlternativeUserAttributesId(); aua.Id.AttributeName = name; aua.Id.User = curUser; aua.AttributeValue = value; aua.User = curUser; curUser.AlternativeUserAttributes.Add(aua); </code></pre> <p>I get an error about that the row count was expected to be 1 but was zero, and when I try to save only the AlternateUserAttributes as its self using Save, I get the this error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index</p> <p>Both attempts are yelding a INSERT for the new Item but i keep getting these errors. Is there anyone that can help?</p>
