If you ever get this error it could be because your property mappings are mapped to the same column.

<property name="FirstName" column="FirstName" type="string" not-null="true" />
<property name="LastName" column="FirstName" type="string" not-null="true" />

This will cause this error, the fix is to map your properties correctly.

<property name="FirstName" column="FirstName" type="string" not-null="true" />
<property name="LastName" column="LastName" type="string" not-null="true" />
