Of course I should post my mappings to, sorry
<class name="Receipt">
<id name="ClientId" access="field.camelcase-underscore"
type="System.Guid" unsaved-
value="00000000-0000-0000-0000-000000000000">
<generator class="guid" />
</id>
<set name="Entries" access="field.camelcase-underscore"
inverse="true" cascade="all-delete-orphan">
<key column="ReceiptId" foreign-key="FK_Receipt_ReceiptEntry" on-
delete="cascade"/>
<one-to-many class="Hogia.CashRegister.ReceiptEntry,
Hogia.CashRegister"/>
</set>
</class>
<class name="ReceiptEntry">
<id name="ClientId" access="field.camelcase-underscore"
type="System.Guid" unsaved-
value="00000000-0000-0000-0000-000000000000">
<generator class="guid" />
</id>
<many-to-one name="_parent" access="field" class="Receipt"
column="ReceiptId" not-null="true"/>
</class>
